Dear Chun-Ting
Thanks for reporting this. We changed the GCM to contain only filenames by default, because users were running out of memory. I'll have a look into this and see if there's an issue with updating the original DCMs. In the meantime, you can run the following code:
% Load the GCM of filenames
load('GCM_xxx.mat');
% Convert filenames -> DCMs
GCM = spm_dcm_load(GCM);
% Iteratively fit using PEB
GCM = spm_dcm_peb_fit(GCM);
% Save
Save('GCM_xxx_estimated.mat', 'GCM');
Best
Peter

Subject: [SPM] DCM Estimation of GCM.mat in v7219
Dear Users,
I updated to v7219 recently and tried to run a DCM/PEB analysis.
In the earlier version the estimated DCM structures would be collated into a large GCM.mat for the second level PEB analysis.
In the current version, after Full+BMR PEB estimation, the command window output looks the same as the earlier version, but the GCM.mat contains only column(s) of DCM.mat paths, and the individual DCM.mat files are not updated with estimated information.
I wonder if in the batch "DCM Estimation", I should change the "output" option to Overwrite Existing Individual DCM Files instead of Create Group GCM_*.mat file, to have the individual DCM files updated and I could create a GCM.mat by collating the path of DCM files myself for the PEB analysis?
Thank you for the information.
Best regards,
Chun-Ting Hsu
