Configurable Application for Measurements, Experiments and Laboratory Systems

NOMAD CAMELS is a configurable measurement software, targeted towards the requirements of experimental solid-state physics. Here many experiments utilize a multitude of measurement devices used in dynamically changing setups. CAMELS allows to define instrument control and measurement protocols using a graphical user interface (GUI). This provides a low entry threshold enabling the creation of new measurement protocols without programming knowledge or a deeper understanding of device communication. The GUI generates python code that interfaces with instruments and allows users to modify the code for specific applications and implementations of arbitrary instruments if necessary. Even large-scale distributed systems can be implemented. CAMELS generates FAIR-compliant data including rich metadata. NeXus standards, immediate NOMAD integration and hence a FAIRmat-compliant data pipeline can be readily implemented.

1.8.5

Features: - the protocol buttons now have the option to duplicate the protocol (a new protocol-configuration opens with a copy of the old protocol)

Changes: - hiding data-output selection for sub-protocol, simple- and ND-sweep, as only sub-stream works well - made sample selection NOMAD / non-NOMAD more clear - not asking whether to discard changes in protocol if no changes were made (works in most cases, sometimes still asking)

1.8.4

Features: - added functionality to create a new file after a given number of hours (file includes same metadata) - can rename channels and instruments for single protocol ("alias") to allow easier sharing of protocols - can now manually enter resource names for VISA instruments - added more visual feedback for boxes that have validity checks

Changes: - added a possible function that instruments can have to hide settings for a config sub-widget for change config step - reconfigured design of general protocol config - entry name not anymore showing up in filename - now only writing packages for startup when file does not exist yet, might improve startup speed - optics of splitters changed to make it easier to see them - changed the design of the settings window (not affecting any settings)

Fixes: - Change device config protocol step should now work again. - Made Change device config a bit clearer by removing settings that are not changed. - Default API host is 0.0.0.0 instead of 127.0.0.1. This allows all devices on the same network to access the API server. Make sure you firewall settings are adjusted accordingly. - Removed deprecated additional data from Fit-UI - Cannot make a Manual control with a name that is already in use anymore, i.e. not overwriting the old one - now warning when trying to log into central NOMAD as an oasis (which does not work, need to select "central NOMAD" for it)

1.8.1 Fixed broken Plots in Loops

UI-Improvements: - Tabs now have an "x" button to close them (right-click still works)

Fixed: - Fixed plots in subprotocols not updating when called from loops (For Loop, Simple Sweep). - Error message now only appears once when trying to plot and fit something that is not being read - When adding a new protocol, the view does not jump back to the first tab anymore - Fixed broken export to csv files and prevent overwriting of existing csv files. - Deleting tabs now works again

1.8.0 Parallel Async Reading and New Plot Backend

Features: - can now asynchronously read channels during a running protocol

Changes: - Plots now use a different backend. Should make the run engine faster and more stable. Plots now run in their own threads and should not interefere as much with the main protocol execution. - Now saves data files with an .h5 file extension if no NeXus output was enabled. Only uses .nxs file extension if NeXus output is saved to the file. Should clarify that the standard CAMELS data files do NOT follow rigid NeXus standards. - Subprotocols always create a new data stream and entry in the data file

Fixed: - You can now run the same subprotocol multiple times. Each subprotocol execution creates it own data stream. This means the datafile has separate entires for each subprotocol run - When dragging / dropping a step in the protocol sequence, the moved step is now selected afterwards - Cannot drop a step in a simple sweep anymore - Manual controls could not work with channels that need to call trigger, now fixed - Made aborting a protocol more stable - Generic set and read manual control now closes its thread more stably - Fixed expression evaluation for subprotocols - Protocol and device description field is now max 130px high. After that it becomes scrollable.

This filters all available channels, variables or functions by the string that is entered. - Added the Execute Python File loop step. This allows the user to specify a Python file and a Python environment to run the file with. The environment can either be the same as the one running CAMELS (default), a different already existing one, or is created dynamically by giving it the required packages and versions. The Python file can return (realized by printing) a dictionary with key value pairs. To read these, give the name of the key in the Values returned by the Python file list. - Added a tab that allows you to add new tabs simply by clicking it. - Point Distance can now be used for For-loops.

Changes: - Running a protocol with a subprotocol also builds the subprotocol now. This makes it easier to change sub-protocols for more complex measurement routines. - Start-min-max-stop sweeps in a for loop now behave differently, the number of points is now the total number of points, not the number between min and max

Fixed: - Description fields now change their size dynamically. - Filtering the channels by name does not break if no matches were found. - Filtering Set Channels now does not reset the value if the channel does not match the query. - Fixed the hide/show information when installing instruments
