Hi!
The use of single-band reference images is currently not supported with multi-echo data in fmriprep. From previous discussions (links below), I get the impression that this decision was taken mainly due to a dataset that was missing sbrefs for the first/shortest echo (but it was a long discussion, I might have missed some points).
We’re collecting multi-echo multi-band data with sbrefs for each of the 3 echos, and as the contrast of course is massively better in the sbrefs (see below for an example), I was wondering whether there has been any discussions about re-enabling sbref support for ME-data in fmriprep? Or are sbrefs considered “superfluous” in an ME-context as one can achieve good coregistration using the --t2s_coreg
flag?
_echo-1_bold.nii.gz
, first volume
_echo-1_sbref.nii.gz
On a related note, it seems like fmriprep currently doesn’t detect the multi-echo sbrefs at all. Would expect to get line 323-324 (from fmriprep/workflows/bold/base.py
)
however we get line 335
With this BIDS-naming
Thanks!
