Some analyses run very slowly over the network. This is mainly due to slow write times where spm functions write slice-by-slice. The intensive network writing can also cause file errors.
A local processing option is implemented in some functions.
Function | Comments |
|---|---|
fMRI slice timing | Example at UCLA: slice timing over 420 HCP files Network: 5840 seconds Local: 620 seconds |
fMRI Drifter | Less important since 2022 speed-up (reading volumes) |
fMRI smoothing | Example at UCLA: smoothing 420 HCP fMRI files Network: 1200 seconds Local: 390 seconds (3 x speed-up) |
This option copies files to a local folder (e.g., C:\matlab\spm12\toolbox\CSPM\temp\auto 2022-07-21 14h09m49s\), performs the processing, saves the output files back to the network folder, and deletes the local files and folder.
