new version pandas.io.common.EmptyDataError: No columns to parse from file

[mariemorel]

Dear Carine,

I have recently updated pcoc with the new version and since then, I cannot run some of my datasets anymore. The sedges c3c4 dataset from Besnard et al still runs but I have a rhodopsin dataset that used to run with the previous version and now I get :
Command error:

  pandas.io.common.EmptyDataError: No columns to parse from file

my command :

S=`cat scenario_pcoc_noacr.txt` 
pcoc_det.py -t tree-rerooted.nhx.txt -aa lessgappy.align_reroot.fa.txt -cpu 4 -o output_pcoc -m $S -f 0.8 -f_oc 0.5 --max_gap_allowed 20 -est_profiles C10

I have tried to discard as many gaps as possible but I don't think it is the issue here. I analyzed my fasta file and the tree and I really cannot see the problem.

In the meanwhile, I am using the old version.

Thank you a lot for your answer and your work!
