Hi Dr. Glasser, I moved everything I need to open under the /bin just to make sure that I did not mess up with the path. An update: I am now able to use most .dscalar and .dtseries files for participants with ciftiopen. Yet I don't know what I did to get it right. I also succeeded in open "melodic_IC.dscalar.nii" for ICA d=50, yet I got the same error for "melodic_IC.dscalar.nii" for ICA d=25. This inconsistency confuses me.
