Error using check_license_chisep

[jadenecke]

When running the chisep_script on a cluster over a larger dataset i get the following Error (sometimes):

Error using check_license_chisep
There are no license files

Error in QSMnet

Error in QSMnet_general

Error in Chisep_script (line 104)

Running the script again everything works fine and I get no errors. At the moment I am concurrently running 30 Sessions as individual jobs. How is this error produced and is there a way around it?

Solution: copy the chisep folder to a new location and have each process use their own copy of chisep.
It seems like the license files are blocked while executing the matlab code, so that each process trying to load it while there is another process currently using it, throws an error. When you have a cluster running it, its is by chance that two jobs arrive at the same code line at the same time. This is why the issue occurs seemingly random.
