Hi Francois,
Thanks for the prompt reply.
The test that you have added is certainly helpful as I have noticed something strange.
For both the "group analysis" files and individual subject files, I get the same error message:
BST> Warning: 1 file(s) not found in database.
I have followed your suggestion of reloading the files as well and the error still persists.
The contents of both the files are here -
- Subject file
- Projected and spatially smoothed (same subject, same epoch)
- TF plot after restarting bst
The data are from a continuous listening experiment so there are no ERP components per se but this does look a bit odd (perhaps its just this subject). Our aim is to use the PAC (and tPAC) tools in bst. I couldn't find any documentation on group analysis using PAC (happy to contribute that if I get this work).
My suspicion is that this error has occurred when the files were written so I probably will have to re-compute dspm. What do you think?
So the revised pipeline will have to be -
- preprocess data
- Import epochs into database
- Compute dspm
- Use ROIs to compute PAC
Key question here is how do we know that we are comparing the same ROI between participants (i.e., due to differences in individual anatomy. Some participants have individual MRI, some don't)?
Apologies for writing an extensive reply but I really do appreciate your help.
Cheers
