Getting error when counting splice sites

[fburdet]

Hello,

I installed the package on an Ubuntu 22 server.

When running
fds <- countRNAData(settings)
with my own data (ONT bam files), the first steps work ok, but then I get

Mon Aug 29 17:58:49 2022: In total 239257 splice sites (acceptor/donor) will be counted ...
Error in reducer$value.cache[[as.character(idx)]] <- values :
wrong args for environment subassignment
In addition: Warning message:
In parallel::mccollect(wait = FALSE, timeout = 1) :
1 parallel job did not deliver a result

What could be the issue?

Thanks

I get the same error running FRASER via DROP. Happens only intermittently. I think its inadequate memory?

Hi, yes, we have seen this happening, most likely due to the program running out of memory. Can you please try rerunning it? If using DROP, use the -k parameter on the snakemake run, and be sure to have recount: FALSE in the config file.

Hi,

I am having the same error while counting split reads. My input is ~100 bam files with >100M reads each. I tried to run with and without parallelization, and also to allocate more memory. It did not help. Could you advise what I could try or any work arounds?

Thank you!
