camisim encountered an error when specifying the --hmm_model parameter in pbsim2
Closed this issue · 3 comments
Hi,
I modified script "readsimulationwrapper.py" to use pbsim2 to simulate pacbio CLR reads.
When I set "--sample-fastq" parameter to simulate pacbio HiFi reads, it work well. But when I set "--hmm_model" parameter , it encountered an error.

How to deal with it?
Thank you in advance.
Hi, without knowing what exactly you changed this is very hard to tell, is the above screenshot the only position in the code you changed? Unfortunately, the PBsim version for which CAMISIM was implemented is quite old (i.e. not even PBsim2) and the output of PBsim may have changed in the meantime, so the subsequent scripts are likely to fail. The error you encounter stems from the anonymisation step, but it is my guess that something is wrong with the data before that already (e.g. there is no data here /tmp/tmpwe1mm89g/2024.01.10_19.31.13_sample_0/reads).
You can try running CAMISIM with the -debug option to get more details as to why CAMISIM may have crashed, but unfortunately changing only the snippet above is unlikely to work for PBsim2
Yes, that is the only position in the code I changed. And I ran CAMISIM with -debug and returned traceback information.

Adding PBSim2 to CAMISIM is on my todo list (#131), but it has not been completed yet. Your error most likely occurs because of some changes in PBSim2 in comparison to PBSim1 (most likely in terms of output, e.g. file names or formats). Just changing the command line options and the executable unfortunately will not suffice to implement PBSim2 into CAMISIM.
My assumption is that there probably are some more errors "hidden" in the log, e.g. it is possible that PBSim2 did not simulate any reads at all which makes CAMISIM not finding files to anonymize. If you add the complete log I might be able to confirm this.
Note however that while I plan on implementing PBSim2, I will not give a concrete timeline as to when this is going to happen and if the error is not easily fixed and you don't want to wait, you would have to implement PBSim2 yourself (i.e. creating a new PBSim2 class inheriting from ReadSimulationWrapper and implementing the required methods) - I would love a PR for this.
