2 years ago The error message is caused by the mismatch between the time (4th) dimension of the NIfTI data and the size of the 'TE' variable in the header file.
You can correct the header file by loading the file to matlab, then update the variable and save all the variables, for example, using the following lines in the Matlab's command window
load('sepia_header.mat');
TE = [TE1,TE2,TE3,TE4]; % depends on your data, e.g. 5 echoes -> 5 values
save('sepia_header.mat','voxelSize','matrixSize','CF','delta_TE','TE','B0_dir','B0');Let me know if this can solve your issue.

after loading the files and making the sepia_header file as per suggestions, while starting following error appears:Phase data is loaded. <<<<<<<<<"Magnitude data is loaded. No weighting map is loaded. Default QSM weighting method will be used for QSM. Header data is loaded. Validating SEPIA header... Input SEPIA header is valid. Validating input NIfTI files... There was an error! Please check the command window/error message file for more information. Error using SepiaIOWrapper>check_input_dimension (line 481) Input NIfTI data and SEPIA header do not have the same number of echoes. Please check these files.

How do one change number of echoes in header, if needed?
