Usage¶
ME-ICA minimally requires:
- acquired echo times (in milliseconds), and
- functional datasets equal to the number of acquired echoes.
But you can supply many other options, viewable with meica -h
.
Command line options¶
Attention
Make sure your datasets have slice timing information in the header.
If not sure, specify a --tpattern
option.
Check AFNI documentation of 3dTshift to see slice timing codes.
Tip
FWHM smoothing is not recommended.
tSNR boost is provided by optimal combination of echoes.
For better overlap of ‘blobs’ across subjects, use non-linear standard space normalization with --qwarp
.
