R package to design PCR primers for TAP-seq

https://github.com/benstory/TAPseq/blob/master/

# TAPseq
An R-package to design PCR primers for TAP-seq published in
[Nature Methods, 2020](https://www.nature.com/articles/s41592-020-0837-5). `TAPseq` is available
through [Bioconductor](http://bioconductor.org/packages/release/bioc/html/TAPseq.html).

## Installation

This package requires local installations of Primer3 and BLASTn. `TAPseq` has been developed and
tested using Primer3 v.2.5.0 and blastn v.2.6.0. It's strongly suggested to use Primer3 >= 2.5.0!
Earlier versions require a primer3_config directory, which needs to be provided whenever calling
functions interacting with Primer3. Source code and installation instructions can be found under:

Primer3:   
BLASTn: 

Please install these tools first and add them to your `PATH`. If you don't want to add the tools to
your "global" `PATH`, you can add the following code to an `~/.Rprofile file`. This should add the
tools to your `PATH` in R whenever you start a new session.
```
Sys.setenv(PATH = paste("/full/path/to/primer3-x.x.x/src", Sys.getenv("PATH"), sep = ":"))

Sys.setenv(PATH = paste("/full/path/to/blast+/ncbi-blast-x.x.x+/bin", Sys.getenv("PATH"), 
                        sep = ":"))
```

The R-package and its R dependencies can be installed from Bioconductor using the `BiocManager`
package. This requires `R >= 4.0.0`.
```
if (!requireNamespace("BiocManager", quietly=TRUE))
    install.packages("BiocManager")
BiocManager::install("TAPseq")
```

`TAPseq` can also be installed directly from GitHub using the `devtools` package. This also allows
to install an older version, which work for `R >= 3.5`.
```
install.packages("devtools")

# latest development version
devtools::install_github("argschwind/TAPseq", dependencies = TRUE)

# installing a previous version for R >= 3.5
devtools::install_github("argschwind/TAPseq@r_release_3.5", dependencies = TRUE)
```

## Examples
An example of the TAPseq primer design workflow can be found in a vignette. To view the vignette,
run the following command (assuming vignettes were built when the package was installed).
```
vignette("tapseq_primer_design", package = "TAPseq")
```

Examples of how to select and evaluate target genes to identify cell populations can be found in
a separate vignette. This requires that the additional dependencies are installedl, which should be
the case if the package was installed with building vignettes and suggested dependencies.
```
vignette("tapseq_target_genes", package = "TAPseq")
```
