I just ran trac-all on my data and am trying to use tractstats2table to run some tract-based group level analysis. 

I have created a text file with the full paths to each conditions stats file (attached below and tried to run the following command

tractstats2table --load-pathstats-from-file /Volumes/DANIEL/trac/stats_info/stats_rh.unc.txt --overall --tablefile /Volumes/DANIEL/trac/stats_info/rh.unc.All.table

However, I get the following error message.

Parsing the .stats files

Traceback (most recent call last):

  File "/Applications/freesurfer_dev/bin/tractstats2table", line 347, in <module>

    pathway_subj, measure_value_map = parsed.parse()

  File "/Applications/freesurfer_dev/bin/fsutils.py", line 288, in parse

    val = float(strlist[1])

ValueError: could not convert string to float: 'y'

Could someone please provide me some guidance on how to troubleshoot this?
