Dear Saad,

I ran the fdt_matrix merge with the list of matrix full paths but it could not run successfully. The command and information were as follows.

$ /u1/local/fsl/bin/fdt_matrix_merge list_matrix output
merge 3 files

terminate called after throwing an instance of 'MISCMATHS::SpMatException'
  what():  SpMat::SpMat::SpMat(string& fname): Last row must have zero value and indicate matrix size
Aborted

Could you please tell where is the problem?

Thanks a lot!

Best regards,

Xinyang

The input should be a text that contains a list of file names (one per matrix that you want to add) with the full path to the file location.

Dear Saad,

Hi, thanks a lot for your reply.

I put all the matrix file directory into a txt file and ran but failed. The information says, "terminate called after throwing an instance of 'MISCMATHS::SpMatException'" and "Last row must have zero value and indicate the matrix size".

Could you please provide more detailed information about this command? How should I produce the AsciiListOfMatrixFiles with the matrices?

Thanks.

Best regards,

Xinyang

Hi - you can use

 fdt_matrix_merge <AsciiListOfMatrixFiles> <outputMatrixFile>

Cheers

Dear FSL experts,

Hi, is there any FSL command to sum up a group of 2D fdt_network_matrix which came out from multiple parallel runs of probtrackx2? Thanks!

Best regards,
