Hi Albert,
Are you running HCP Pipelines through QuNex or are you running the pipelines directly. This is a QuNex forum, if you are using the second option https://groups.google.com/a/humanconnectome.org/g/hcp-users is the correct place to go.
If you are using QuNex, please read QuNex Issue Reporting Guide and provide as much of the requested information in there as possible.
Thanks!
Cheers, Jure
