I have downloaded ADHD200_CC400TCs_filtfix.tar of the ATHENA pipeline.

1. I see that each file, for example, subject OSHU>114123>, has 6 files. 3 prefixed with- sfnw...  and the next 3 with- snwm... What do they mean? I need to generate functional connectivity matrices for each subject. Can I just take any of the 6 .1D file?

2. I am unable to understand the column names in the phenotypic file. It has values 0-3. Is there a legend to understand the column names and the expected values ?

3. Some files on the download page have test data separately. Why are these files kept separately ?

4. How do I generate functional correlation matrices for all the files I have downloaded at once?
