Kissplice "Finding BCCs" and no output fa or tsv files

Question

[audrahuffmeyer]

I am running the kissplice program on 8 fastq files. Everything runs until "Finding the BCCs" (see summary log below). Then the program stops and there is no output. I do not get any tsv files. This has happened twice now, do I need to change the --timeout parameters?

Thanks in advance!

Dear audrahuffmeyer,

There is a common problem in this step if your graph is too large and your stack size is not sufficiently large for the several calls of a recursive algorithm. To solve this problem, try to run (in Unix systems):

ulimit -s unlimited

before running KisSplice.

If you are using a Mac OS, try:

ulimit -H -s

to find the highest value possible for the stack size and then:

 ulimit -s <highest_value>

to set the new value of the stack size.

Could you please tell me if this worked for you?

Thanks!

Kind regards.

Thank you! This solved the problem!

Best, Audra
