Hi,
Setting the trinity_kmer_length option in the config file leads to this error from trinity:
ERROR, don't recognize parameter: --KMER_SIZE
Based on this, I believe that --KMER_SIZE should be changed to --__KMER_SIZE on line 1093 of tracer_func.py.
When running Trinity standalone instead of Tracer, using --__KMER_SIZE instead of --KMER_SIZE works.
Thank you!
