External Email - Use Caution

Sorry, I realized I used the pathstats.byvoxel.txt instead of pathstats.overall.txt.

Attached is the correct .txt file and the new error I get from the python script called by tractstats2table

pathstats.overall.txt

Hello,

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.

Traceback (most recent call last):

val = float(strlist[1])

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

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