kmc std::bad_alloc about iva

[ChrisHIV]

Sorry the delay. Yeah that was it - 2GB in the original VM, fixed by increasing it to 4GB. Thanks!

That looks like a kmc issue. If that tmp directory is still there you could double check by running kmc -fa -m4 -k95 -sf1 -ci25 -cs1000000 -cx1000000 /home/user/TestIVA/iva.out/tmp.common_kmers.ile75uwy/reads.fa kmc_out $PWD, but I expect you'll get the same result.

Could also be worth cloning the IVA repo and running python3 -m unittest iva.tests.kcount_test. TestKcount.test_run_kmc and seeing if that throws an error.

[ChrisHIV]

I can't test the former as the --keep_files option is ignored by --test. For the latter:

$ python3 -m unittest iva.tests.kcount_test. TestKcount.test_run_kmc

Sorry, typo. There was an accidental space in there. Try:

python3 -m unittest iva.tests.kcount_test.TestKcount.test_run_kmc

OK

???

I didn't expect that! That suggests kmc is running ok. Bear with me, I'll have to get a VM with Ubuntu 16.04 up and running to test this out some more. I guess you followed this? https://github.com/sanger-pathogens/iva/wiki/Installation-notes-for-Ubuntu

[ChrisHIV]

For the most part, though I installed samtools differently, and I'd installed some other stuff first. I'll go through the full set exactly as written on a clean Ubuntu, and see if I get the same bug.

[martinghunt]

OK, let me know and if you do still get it then I'll take a look.

Following the instructions verbatim on a clean 16.04.3, iva --test TestIVA gives

Running iva in test mode...
Copied input test files into here: /home/testiva/TestIVA
Current working directory: /home/testiva/TestIVA
Running iva on the test data with the command:
/home/testiva/.local/bin/iva --threads 1 --pcr_primers hiv_pcr_primers.fa -f reads_1.fq.gz -r reads_2.fq.gz iva.out
The following command failed with exit code 1
/home/testiva/.local/bin/iva --threads 1 --pcr_primers hiv_pcr_primers.fa -f reads_1.fq.gz -r reads_2.fq.gz iva.out

The output was:

The following command failed with exit code 134
bash run_kmc.sh

The output was:

  what():  std::bad_alloc

Cloning the git repo and running python3 -m unittest iva.tests.kcount_test.TestKcount.test_run_kmc, I now get an error instead of success (perhaps because the default instructions use kmc 2 instead of 3?):

The following command failed with exit code 134

I reproduced that error (using vagrant ubuntu/xenial64 VM), with the VM having 2GB of RAM.

Putting the RAM up to 4GB fixed it and iva --test TestIVA ran through ok. How much RAM does your machine have?

For completeness, here's the bash history:
