bvals and bvecs for the diffusion MRI data
Hi -

I hope this email finds you well. We are trying to use the U01 diffusion data and generate metrics other than the ones provided; unfortunately there are no bvec or bvals in th DWI data folder. Could you please share with us these files? Please, let me know if there is anything I can clarify!

Thank you so much -
Adnan

RE: bvals and bvecs for the diffusion MRI data

For each subject that we provide DWI data, there is a file with subjects ID followed by either `DRBUDDI_up_final.bmtxt' or `DRBUDDI_final.bmtxt'. These files can be used to generate the bval and bvec files using the DIFFPREP command from the TORTOISE software.
