cutadapt fails. when removing primers

Huda_Ghori · May 30, 2020, 12:51pm

HI

I am using the command to cut amplicon primers from my sequences:
qiime cutadapt trim-paired
–i-demultiplexed-sequences SM_16S.qza
–p-cores 8
–p-front-f CCTACGGGNGGCWGCAG
–p-front-r GACTACHVGGGTATCTAATCC
–o-trimmed-sequences primer-trimmed-SM_16S.qza
–verbose

my job fails and gives the following out put

[8<----------] 00:00:01 35,585 reads @ 29.9 µs/read; 2.00 M reads/minuteTraceback (most recent call last):

See above for debug info.

I thought maybe my sequences did not import correctly so I imported it again but I am still getting the same output. I also validated my file and it says that the file is valid.

I do not understand the error.

Please help

Hi @Huda_Ghori

Could you try this command to test if your seqeuences have been imported correct.

qiime demux summarize \
--i-data SM_16S.qza \
--o-visualization SM_16S.qzv

Hi @Huda_Ghori! Is there any more verbose output available? It looks like we are missing the first half of the log - can you please attach here - thanks!

PS - the first half of the cutadapt starts with a line or two like this:

This is cutadapt 2.8 with Python 3.6.7

HI thankyou for replying

this is my output from demux summarize command

thermokarst · June 3, 2020, 2:15pm

Hi @Huda_Ghori - I’m not really sure what @sixvable was asking for, but I am looking for the full log when running qiime cutadapt trim-paired with the --verbose flag. Thanks!

Great, thanks for that, @Huda_Ghori!

It looks like maybe cutadapt is suffering from some kind of catastrophic failure - is it possible that you are specifying more cores than you have available on your system? What happens when you run with 4 (or 2)?

Keep us posted!

Hi @thermokarst

I ran it again with 2 cores and it showed the same error :

I’m still not sure what the issue is here - cutadapt is failing catastrophically, with no traceback or error message (which is unusual for cutadapt). Would you be willing to share your files with me (you can send a download link to me in a direct message)? That would help with diagnosing if the issue is related to your computation environment, the data, or something else entirely.

Thanks!
