Sorry about that. Copy-pasted error message. Fixed now - the tool now assumes that output file format should be P61A, even if doesn't start with 'p61.' 'p61a.' or end with '.p61' or '.p61a'

Possibly due to unused patterns ?

You're right. Unused patterns were not fully supported. Feature added in V0.2 (attached).
