Dear HCP experts,
I am experiencing difficulties reading cifti into matlab.
For the ICA maps (melodic_IC.dscalar.nii). I used:
cifti=ft_read_cifti('melodic_IC.dscalar.nii')
The error I got was:
Error using read_nifti2_hdr (line 56)
cannot open melodic_IC.dscalar.nii as nifti file, hdr size = 1684628319,
should be 348 or 540
I also tried:
cifti=ciftiopen('melodic_IC.dscalar.nii','wb_command')
and I got
ERROR: error reading NIfTI file
/workbench/bin_rh_linux64/melodic_IC.dscalar.nii:
/workbench/bin_rh_linux64/melodic_IC.dscalar.nii is not a valid NIfTI file
wb_command -cifti-convert -to-gifti-ext melodic_IC.dscalar.nii
/tmp/tpe16b84a6_70fd_4d0b_80c7_1daf1d5c79b7.gii: Signal 127
Error using read_gifti_file (line 17)
[GIFTI] Loading of XML file /tmp/tpe16b84a6_70fd_4d0b_80c7_1daf1d5c79b7.gii
failed.
Error in gifti (line 71)
this = read_gifti_file(varargin{1},giftistruct);
Error in ciftiopen (line 31)
cifti = gifti([tmpfile '.gii']);
Errors when opening other cifti files are different, for example
cifti=ciftiopen('rfMRI_REST1_LR_Atlas_hp2000_clean.dtseries.nii','wb_command')
Undefined function 'file_array' for input arguments of type 'char'.
I run all commands in workbench's bin. My workbench is v1.0. My gifti
library was just downloaded so no reason to believe that it is not
up-to-date.
Any help is appreciated.
Best,
Cherry
