      Hi BDP developers,
      I put all my files in one folder and downloaded the exercises dataset and was trying to run bdp,
      so this is what I have
      Error message: the bvec file does not seems to contain valid gradient vectors: 2523412.dwi.bvec
      the generator error message is:Unknown text on line number 1 of ASCII file 2523412.dwi.bvec
      Error help/resolution: BDP relies on pre-defined file format and filemap pattern. Please refer to error message above. You can find more details of file format at …

      How do I continue?
      Thanks

      It looks like the bvec file is not in the format that can be read by BDP
      Here is a sample of what BDP looks for: http://brainsuite.org/examples/siemens_20.txt

      You might have to reformat it to this or I would suggest using dcm2nii to convert your dicoms to nifti

      Hi Sychoi,
      I downloaded this data from
      http://brainsuite.org/tutorials/dtiexercise/

      IT should be matched, right?
      Thanks.

      oh, somehow it is running fine now. I will let you know when there are other issues I am not sure how to solve. Thanks.

      PS. I run my own data and got bfc.nii.gz, but how to get .dwi.bval and .dwi.bvec and dwi.nii.gz file to fun BDP?

      Bvalue (.bval) and Bvector (.bvec) files are sampling protocol information of your dwi file. This should be provided as input to run BDP – It should have been published along with your diffusion data.

      It has not been published yet. Where do I get them?

      You should have got them along with your data.
