Hi there, I've encountered a problem when dealing with preprocessed r-fMRI HCP
data by SPM8. To be specific, data on many time points can not be recognized by
SPM, and the MATLAB command window showed an error "file too small" . Beside
this, the last few frames of a run looked weird when viewing
Hello every one
I ran FSL MELODIC single session ica on connectome project Q1- single subject
preprocessed rest-fMRI data, but in the result MELODIC report page,the ICA tab
is empty.
I didn't change default options in fsl melodic except in pre-stats tab, i
disabled all the preprocessing optio
Hi - what's in the report_log.html file?
Cheers

Hi - I think you probably need to take this query to the SPM email list I'm
afraid - we haven't used SPM so far in the HCP, so don't have experience with
how it performs on HCP data.
Cheers, Steve.

hi all
In connectome fMRI data,what is difference between R-L phase encoding and L-R
phase encoding?
which one should i use in my analysis?or should i combine them somehow?
there is also an other file named rfMRI_REST1_LR_hp2000_clean.nii,i am
confused,which file should i use in my analysis?
tha
We use all four resting state runs and we use the CIFTI ${fMRIName}_Atlas_hp2000_clean.dtseries.nii data which has been cleaned with ICA+FIX. When using runs with a different phase encoding direction, it is important to remove the mean image first. We
then temporally concatenate multiple runs
Looking at the WarpFields in the
DistortionCorrectionAndEPIToT1wReg_FLIRTBBRAndFreeSurferBBRbased/FieldMap
directory,
the "WarpField" looks good and has data,
The "WarpField_01" and "WarpField_02" are both empty
From: hcp-users-boun...@humanconnectome.or
Are there only two of those files? It¹s not really possible for WarpField
to have a warpfield in it (that looks like a field map with a vaguely
brain shape inside it) but for the WarpField_01 and Warpfield_02 not to
have any data in them (did you check all their volumes)?
Peace,
Matt.

Hi Stuart,
I have fewer answers than questions, but it seems like at the end of this, you
want your source (fsaverage) parcellation mapped onto the HCP subjects'
surfaces, and then projected from surface to volume (subject's orig/magnet
space or MNINonlinear stereotaxic space?).
The HCP pipeli
There are 6 files in the subject I am looking at, labeled Warpfield_01 to 06,
in additino to Warpfield.nii.gz.All have 3 volumes, with the 2nd volume
having the fieldmap/brain image in each. Warpfield images 4-6 look much like
the final Warpfield image, whereas Warpfield images 1-3 appear t
Okay, that sounds like things are producing the expected outputs. As to
why the correction isn’t quite as good, you could check to see how
different the corrected spin echo images look. These should give you an
idea of how well the distortion correction worked:

When you email the SPM list, you will need to provide the following:
(1) What specific files could not be opened?
(2) What size are the files?
(3) What did you mean by "weird"?
I suspect the files are more than 2GB, which has been known to cause issues
with some functions in SPM8. These should res
