Re: [Erppcatoolkit-support] Problem merging .set files

[Joseph D. <jd...@ma...>]

Sorry to hear about the problem!  It doesn’t sound like you’re using the Single Cell Files Mode correctly.  The files are supposed to be named in a way that can tell apart the subjects and cells (e.g., TEST01T).  In this case the first four characters indicate the name of the experiment and are ignored.  The next two characters indicate the subject number.  The final character indicates the condition name.  one would write in 5:6 for the subject and 7 for the condition.  Take another look at the instructions in the Tutorial file.
Nonetheless, it shouldn’t be crashing.  At worst it should give you an error message.
Could you send me the names of your files so I can figure out why it is crashing?

Cheers!

Joe
