Issue creating a database with QSDR fz files

[Frank Garcea]

I have processed my DSI data using Hou version July 25, 2026 and have, for 24 participants, QSDR fz files. I'm creating a database for correlational tracking and have no issue creating and saving the database (.dz file). But when I open it in step C2 I get the error warning that 'invalid fib file: Invalid FIB format: cannot find fa0 matrix'.

Visual inspection of each QSDR within step T3 is fine. The FIBs look good--I can see my QA map as an underlay, can manually select tracts or autotrack.

Any idea how I can go about troubleshooting what might be the problem with the creation of the database? Perhaps there is a problem reading the QSDR file?

Thanks,

FG
