Hi,
I'm trying to use the FieldTrip toolbox in MATLAB to load a file (cortex_8196.surf.gii), but I am getting an error that says it is unable to read the file.
This is the line that is causing the error:
sourcemodel = ft_read_headshape('C:\Users\Emmak\Documents\school\bmed_599\fieldtrip\fieldtrip20230204\template\, . . .
sourcemodel\cortex_8196.surf.gii');
This is the error:
Error using read_gifti_file
[GIFTI] Loading of XML file
C:\Users\Emmak\Documents\school\bmed_599\fieldtrip\fieldtrip-20230204\template\sourcemodel\cortex_8196.surf.gii
failed.
Error in gifti (line 89)
this = read_gifti_file(varargin{1},giftistruct);
Error in ft_read_headshape (line 328)
g = gifti(filename);
What might be causing this?
Thanks!
Emma

I would be interested to see what happens if you readstruct() the gii file.

>> readstruct('C:\Users\Emmak\Documents\school\bmed_599\fieldtrip\fieldtrip-20230204\template\sourcemodel\cortex_8196.surf.gii', 'FileType','xml')
ans =
struct with fields:
VersionAttribute: 1
NumberOfDataArraysAttribute: 2
MetaData: ""
LabelTable: ""
DataArray: [1×2 struct]

Hi Emma,
It is a bit difficult to analyse the exact reason for your error without your model file,however as per my understanding there may be multiple reasons such as
  • File path issue
  • MATLAB and FieldTrip version mismatch
  • File corruption
  • Fieldtrip configuration issues
If you have verified that there are no such issues and you have the required dependencies and permissions to access the file, you may try to debug the code and use the step-in function feature to find the cause of the issue.
