kb-python - v0.27.3

General

Bumped ngs-tools>=1.7.3.

`ref`

[DEPRECATION] Split index generation using -n has been fully deprecated. (Thanks to @amcdavid for catching a bug)

`count`

Fixed a minor issue with --workflow kite:10xFB, where bustools project would be called before bustools correct (the order should be opposite). This fix required a bump to the ngs-tools dependency.
Support for --workflow lamanno for -x smartseq3.
[DEPRECATION] Counting using split indices by providing a comma-delimited list to -i has been fully deprecated.
Support for whitelist (-w option) for bulk, smartseq2 and smartseq3 technologies.
Added support for -x 10XV3_ULTIMA.

- Python

kb-python - v0.27.2

`count`

Whitelist for technology -x BDWTA is now provided.

- Python
Published by Lioscro about 4 years ago

kb-python - v0.27.1

General

[DEPRECATION] Support for split indices (with the -n option) will be deprecated in the next major release. It is now recommended to use --include-attribute and --exclude-attribute options, similar to Cellranger's mkref options (https://support.10xgenomics.com/single-cell-gene-expression/software/pipelines/latest/advanced/references), to kb ref to reduce index size and memory usage.

`ref`

A remote URL may be provided as the fasta (genomic FASTA) and/or gtf (gene annotation GTF) arguments. Support from ngs_tools 1.5.13.
GTF is now allowed to have 0-length segments (https://github.com/pachterlab/kallisto/issues/340).

`count`

[DEPRECATION] Technology SMARTSEQ is now deprecated. All future uses should use BULK, SMARTSEQ2 or SMARTSEQ3.
Genes that do not have a gene name will now have their gene IDs in the gene_name column (or the adata.var_names if --gene-names is used).
Support for --workflow lamanno for -x BULK and -x SMARTSEQ2 technologies.

- Python
Published by Lioscro about 4 years ago

kb-python - v0.27.0

General

Added the compile command. See below for more information. (#139)
Fixed an issue where a call to kallisto would hang indefinitely due to a full stderr buffer.
Changed docstring style to Google-style. Added typings to all functions.
Updated kallisto binaries to v0.48.0.
Updated bustools binaries to v0.41.0.
Added binary compatibility checks. If a binary is incompatible, kb compile is suggested.

`compile`

This command can be used to compile the kallisto and/or bustools binary from source. At the most basic level, it downloads the latest release source distributions from the respective GitHub repositories, compiles them, and places them where kb can automatically detect them.
The target positional argument specifies which binary (or both) to compile. Possible values are kallisto, bustools and all.
The --url optional argument may be provided with a URL to a remote archive that will be used instead of the latest GitHub release. When this option is used, target may not be all.
* The --ref optional argument may be provided with a commit hash or git tag. When this option is used, target may not be all.
The -o optional argument may be used to place the compiled binaries in a different directory. Note that if this option is used, --kallisto and --bustools options will have to be set appropriately when running ref or count.
The --view option may be used to simply view what binaries (their locations and versions) will be used by kb.
The --remove option may be used to remove existing compiled binaries.
The --overwrite option may be used to overwrite existing compiled binaries.
The kallisto compilation follows https://pachterlab.github.io/kallisto/source and has the same dependencies.
The bustools compilation follows https://bustools.github.io/source and has the same dependencies.
The --cmake-arguments argument may be used to pass in a string of additional arguments to pass directly to the cmake command. For instance, to manually specify additional include directories, --cmake-arguments "-DCMAKE_CXX_FLAGS='-I /usr/include'"
Note that the compilation is performed in shared mode, which means the binary will contain links to shared libraries (i.e. not statically linked).

`ref`

Added --include-attribute and --exclude-attribute options which can be used to include/exclude specific GTF entries based on their attributes. The argument to these options must be in the form of a key:value pair, where key is a GTF attribute name and value is the value of the aforementioned attribute to include/exclude. Only one of these two options may be specified, and each option may be specified more than once. When multiple --include-attribute are provided, GTF entries that have any one of the attributes will be processed. When multiple --exclude-attribute are provided, GTF entries that have any one of the attributes will not be processed.

`count`

Added --filter-threshold option to specify the barcode filter threshold. This option may only be used when also providing --filter bustools and indicates the minimum number of times a barcode must appear to be retained from filtering. (#142)
Added --strand option to override automatic strandedness setting by kallisto bus. Available options are unstranded, forward, and reverse.
Changed the transcript_ids column to be a semicolon-delimited string instead of a list (only applicable when --tcc is provided) as a workaround for an issue with writing lists to h5ad with h5py>=3. #141
Added BULK and SMARTSEQ2 technologies. The two technologies behave identically. The FASTQs may be provided either directly via command-line (only for multiplexed samples), in which case kb will perform demultiplexing, or as a single batch definition text file (only for demultiplexed samples). See https://pachterlab.github.io/kallisto/manual section about batch.txt for formatting. This batch textfile may also contain remote urls to FASTQ files, which will be streamed for supported operating systems. Additionally, added --parity, --fragment-l and --fragment-s options, which may only be provided for these technologies. The first must always be provided, indicating the parity of the reads (single, paired), and the latter two may only be provided when --parity single is also provided, specifying the mean length of the fragments and standard deviation of the fragment lengths.
DEPRECATION The SMARTSEQ technology has been deprecated and will be removed in the next release. Instead, SMARTSEQ2 should be used. See previous point for more information.
Added SMARTSEQ3 technology.
The full binary path is used for --dry-run instead of an alias.
Added --umi-gene option, which deduplicates UMIs by gene. Can not be used with smartseq or bulk technologies.
Added --em option, which estimated gene abundances using the EM algorithm. Can not be used with smartseq or bulk technologies, or with --tcc.
Fixed an issue that occurs when the -o option to bustools count already exists, but as a directory. For instance, counts_unfiltered/cells_x_genes. Such folders are removed before running the command.
Improved output file validation so that all expected files must exist.
Added --gene-names option, which may only be used with --h5ad or -loom and not --tcc. By specifying this option, the output h5ad or loom matrix will be aggregated by gene names instead of IDs.
Added support for the following technologies: BDWTA (BD Rhapsody), SPLIT-SEQ, Visium (10x).

kb-python - v0.26.4

`count`

Hotfix for 10x Feature Barcode map when -x 10x:FB (#146)

- Python
Published by Lioscro over 4 years ago

kb-python - v0.26.3

`ref`

Fixed an issue with a dangling keyword argument when concatenating files (#132).

`count`

Fixed an issue where using -x smartseq would check for the --nucleus flag, which was deprecated in the previous version (#133).

- Python
Published by Lioscro almost 5 years ago

kb-python - v0.26.2

General

Deprecated --lamanno and --nucleus flags. Use --workflow instead.
Updated setup.py so that tests don't get installed.
Fixed an issue where requirements.txt would not be included in the Pypi upload.

kb-python - [YANKED] v0.26.1

This version has been yanked due to an issue with installation. Do not try to install this version!

General

Added a check for whether the temporary directory exists. If it does, now prints out an error and exits. (#119)
Logging is now handled by a specialized logger implemented in the ngs-tools library, which provides logger namespacing.
Updated supported technologies text and syntax for kb --list so that they are more compact. Added link to the kallisto manual for custom technology definitions.
Updated citation in info.

`ref`

Fixed --tmp option to set the temporary directory properly (#122)
Major refactor of FASTA and GTF parsing. All relevant functions were replaced with appropriate ones from the ngs-tools library. The ones provided in this library are far more robust in dealing with GTF entries (especially missing attributes). FASTA and GTF files no longer have to be sorted nor decompressed. These all result in an approximately order-of-magnitude speedup in splitting the genomic FASTA. Additionally, more helpful error messages are printed, which should help user debuggability.
Fixed an issue where no logging messages were displayed when downloading a reference with -d.

`count`

Whitelists are now provided by the ngs-tools library.

- Python
Published by Lioscro about 5 years ago

kb-python - v0.26.0

General

Added the optional arguments --kallisto and --bustools, which may be used to override the packaged kallisto and bustools binaries. The argument may be a command in the user's PATH, which will be expanded to the full absolute path, or an absolute/relative path to the binary (#109, thanks @apeltzer, @dpryan79, @Maarten-vd-Sande). ### ref
Any spaces in GTF groups are now removed. For instance, if a transcript has ID TRANSCRIPT ID then the resulting transcript sequence will be named TRANSCRIPTID. (#97, thanks @axelalmet) ### count
Fixed an issue where converting the count matrix using --loom and --workflow lamanno would cause an error (#91)
Fixed an issue with parsing FASTQ paths when using -x smartseq, where the second read file would be erroneously used as the first (#114, thanks @jma1991)
Added entries to indicate the current working directory when the kb command was called, along with the kallisto and bustools binary paths and versions in kb_info.json.

- Python

kb-python - v0.25.1

`count`

Fixed loompy does not accept empty matrices as data error when providing --loom with --workflow lamanno (#91)
When using --h5ad or --loom with -x smartseq, the output matrix has genes as columns, instead of transcripts. For genes that have multiple transcripts, the counts are added. (#93)
For -x smartseq, it is now possible to provide a batch TSV instead of FASTQs directly. The batch TSV must contain exactly three columns: cell ID, FASTQ 1 (read 1), FASTQ 2 (read 2).
Added an error when an uneven number of FASTQs are provided for -x smartseq (only paired-end reads are currently supported)
Turned off all logging and warning messages from h5py and anndata.

- Python
Published by Lioscro over 5 years ago

kb-python - v0.25.0

`ref`

Progress bar is now displayed when downloading pre-packaged reference files.
Added checks to provide more useful outputs for common errors, including: 1) when FASTA and GTF chromosomes do not match, 2) when a GTF entry is not parsable, and 3) when either transcript or exon entry for a transcript is missing in the GTF (both are required).
Added -k option to override default (or calculated optimal) kmer length for the Kallisto index.
Added functionality to generate a feature barcode reference for use with the KITE feature-barcoding workflow. To use this option, supply --workflow kite and a feature-barcode to cell-barcode mapping.
Added -n option to be able to split indices into n parts. This reduces the maximum memory used at any given time. Useful for running in memory-limited environments. When the -n option is used, the -i argument is used as the prefix to the n indices generated. Each of these indices are appended with a .i where i is the index number, starting from i=0. When -n is used the built indices must be passed in as a comma-delimited list to kb count (NOTE: this feature is EXPERIMENTAL See count for more details). When -n is used with --workflow lamanno or --workflow nucleus, only the intron FASTA is split into n-1 parts, which are then each indexed separately. The cDNA FASTA is indexed in its entirety and is never split.
Added functionality to build a single index using multiple references. Useful for mixed species experiments. The fasta argument should be a comma-delimited list of genome FASTAs, and the gtf argument should be a comma-delimited list of GTFs, corresponding in position to each genome FASTA.
Added --tmp option to manually specify temporary directory. Otherwise, behavior is identical to previous version (tmp directory at the location kb is executed).
Added support for IUPAC nucleotide code. Note that kallisto replaces non-ACGUT nucleotides to pseudorandom ones. Thanks @Maarten-vd-Sande ### count
Added support for KITE feature-barcoding workflow. The bustools binary was updated to support this feature.
DEPRECATION: The --lamanno and --nucleus flags will be deprecated in the next release. These have been replaced with --workflow lamanno and --workflow nucleus.
All BUS files that are input/outputs are validated before/after running kallisto or bustools. A BUS file is considered valid if it is read with bustools without error and it has positive number of BUS records. This should prevent bustools from trying to sort empty BUS files and crashing (#31).
Added functionality to generate TCC matrices with the --tcc flag.
Added --tcc flag to include reads that pseudoalign to multiple genes.
When running in verbose mode (--verbose), commands are no longer printed with the full path to the bustools and kallisto binaries. These paths are printed once at the start of the program.
Added --dry-run flag, which prints the entire workflow to standard output as shell commands, without actually running them.
EXPERIMENTAL: Added support for multiple indices by passing a comma-delimited list of indices to -i. kb will align the reads to each of these indices and merge the BUS files with bustools mash and bustools merge. This feature is currently EXPERIMENTAL, and there are known issues that cause the loss of reads. This feature will be fully supported in a future release. In the meantime, use at your own risk!
Added --tmp option to manually specify temporary directory. The default behavior has also changed: the default tmp directory is created IN THE OUTPUT FOLDER (specified by -o). Previously, the tmp directory was created where kb was run, which was causing issues when running multiple instances of kb from the same location. Thanks to @Munfred and @kokitsuyuzaki for the suggestion.
kb now outputs a kb_info.json which includes useful run information, such as the commands run and their runtimes.
Added functionality to generate a brief standalone HTML report that includes basic statistics (run_info.json, inspect.json) and quality-control plots (knee plot, elbow plot, pca, genes detected). This feature is available with the --report flag. Using this flag on velocity matrices may cause kb to crash due to high memory usage, and a corresponding warning is printed at the start. Plots for TCC matrices are not supported.
When the matrix is converted to H5AD or Loom format (using the --h5ad or --loom options), the gene/feature names are included as a column in the var of the anndata. Related to #52
Added a --cellranger option, which converts the raw gene matrices to cellranger-compatible format in a separate, cellranger directory for standard workflow (and cellranger_spliced and cellranger_unspliced for velocity and nucleus workflows). Note that cellranger outputs matrices with genes as rows and cells (barcodes) as columns.
Added --mm flag to include bus records that pseudoalign to multiple genes, via the --multimapping flag in bustools count (#57).
None can be provided as the whitelist, which will force kb to use the bustools whitelist command, even if there exists a pre-packaged whitelist.
Added support for Smart-seq reads with -x smartseq. FASTQs are paired by first sorting the list of FASTQ paths in lexicographical order, and taking every two to be a pair. For instance, if 1.fastq 3.fastq 2.fastq 4.fastq is provided, 1.fastq and 2.fastq will be a pair, and 3.fastq and 4.fastq will be another pair. The FASTQ argument now supports glob expressions to make it easier to provide a long list of FASTQs.
