Hello!

Thank you for using QModeling. We are happy you like it and we hope you find it useful.

To the question, have you copied the wfu_packatlas folder to the toolbox folder of SPM? When you press the "Create masks with wfu_pickatlas", the corresponding function looks for the wfu_pickatlas toolbox at the same folder in which QModeling is, that is, whereverSPMis/toolbox. It seems that the function did not find the wfu_pickatlas folder at this location and it has tried to access a wrong path (This is a bug; we have fixed it and uploaded a new version to our web).

Please, let us know if this works.

Kind regards,
Francisco J.
