Pecan on Roadrunner isn’t working correctly.

Talked to Yaamini this morning about her Pecan run being done already and it looks like something didn’t work right. Pecan claims to have run correctly, but produced no .feature files for Percolator to operate on.

I’m running a single instance of Pecan now with the command 

/home/shared/pecan/bin/pecan -b /home/srlab/Documents/DNR_PECAN_Run_1_20170303/Combined-gigas-QC.txt --minCharge 2 --maxCharge 3 --ionTypes y 2017_January_23_envtstress_oyster1.mzML /home/srlab/Documents/DNR_PECAN_Run_1_20170303/Combined-gigas-QC.txt 400.0 405.0 2017_January_23_envtstress_oyster123

and the only output given by Pecan is

screen-shot-2017-03-04-at-8-56-47-am

Pecan does produce a log file which says

I’m not sure if this means there’s an issue with the mzML file or what.
