Hi,
This may seem like a rudimentary topic/question, but I have not been able to find a clear answer and wanted to check before running my analyses.
Context:
I completed all of my preprocessing steps (motion correction, slice timing correction, BET, smoothing, high pass filtering, B0 unwarping; FLIRT for linear reg of func to structural; FNIRT for non-linear reg of structural to standard) in FEAT first so that I could check that these steps were completed successfully before moving into my analysis.
Question:
If I were to copy just the filtered_func_data.nii.gz files into a new directory somewhere else in order to run my group analysis on a different server, would all of the FLIRT/FNIRT efforts be lost? Or is this information somehow embedded in the filtered_func_data.nii.gz file? {I ask this since (1) upon loading the filtered_func_data.nii.gz into fslview, I see that this image file clearly shows no evidence of the transformations actually being performed ... and since (2) the /reg folder created in the .feat directory during the preprocessing in FEAT would no longer be found with the filtered_func_data.nii.gz once it has been copied to it's new location on a different server.}
Follow-up Question.
- If indeed the FLIRT/FNIRT efforts are lost after copying the filtered_func_data.nii.gz files into a new directory, if I were to copy the required structurals into the same directory, could this registration (FLIRT/FNIRT) be completed "again" during the group level analysis in MELODIC?
- Or more simply, while copying the filtered_func_data.nii.gz for each person into the new directory, I could copy the /reg directory created during the FEAT preprocessing along with the it into the new location. Would this take care of making sure the registration completed correctly during the group-level analysis?
Thank you in advance,
Krista Wisner
