Error specifying fieldmaps using aas_addsubject #201

Hello,
I’m trying to specify fieldmaps using aas_addsubject with the following:
aap = aas_addsubject(aap, 'sub-01', ‘sub-identifier, ’fieldmaps',[11 12]);

Tasklist:
<module><name>aamod_get_dicom_fieldmap</name></module> <module><name>aamod_convert_fieldmaps</name></module>

However, the fieldmap modules in the task list do not get executed.

1. Could you please provide an example of the correct way to do this?
2. Is it necessary that other functional series from the scan also be specified at the same time?

Thank you.
Aahana
