So still an error with return code 1? Or just the self-consistency loop error? If just the latter, check this thread — the self-consistency loop might not always be a problem (but the job crashing with error code 1 is).
How long is the job taking to run before it errors?
If you are still getting a job failure with exit code 1, see this thread (or search for others on this forum) — it looks like this issue often occurs if dada2 parameters are not set appropriately — e.g., if reads do not merge.
If that does not work, could you please post your demultiplexed read quality summaries here (in case this is related to dada2 parameters that you are setting/read quality)? We can take a look at these settings.
Thanks!
