Hi Yifei,

The issue there is that, when defining a .txt labels file which includes only the ROI labels (like the original aal.txt file), CONN expects those N labels to match an ROI file with exactly N values (from 1 to N). In any way, there are a couple of other formats that CONN will interpret correctly where you can specify the values-labels association a bit more freely:

1) create a .txt file that contains two space-separated fields, the first is the ROI number and the second the ROI name (without spaces); so something along the lines of:

     19 Supp_Motor_Area_(L)
     20 Supp_Motor_Area_(R)
     57 Postcentral_(L)
     58 Postcentral_(R)
     ...

2) create a .csv file that contains two comma-separated fields, the first is the ROI name (without commas) and the second the ROI number; so something along the lines of:

     Supp Motor Area (L), 19
     Supp Motor Area (R) , 20
     Postcentral (L), 57
     Postcentral (R), 58
     ...

For any of these formats you may include in the .txt or .csv file as many ROI label-value pairs as you wish (they do not need to be limited only to the values present in your ROI file)

Hope this helps
Alfonso
