Dear Tracula Users Does Tracula assume that the number of B0 scans, specified in Step 7.3 of the config file tutorial (below), are the first X number of volumes in the 4Dnii.gz file or will the Tracula routines know from the bvals file where the B0 scans are ordered in the file? For example, I have two runs of 16 directions + 2 B0s each for each of my subjects. I have merged the two runs together and the resulting file has the volumes ordered such that the bvals are entered into Tracula as follows:
0 0 1000 1000 1000 etc 0 0 1000 1000 1000 etc My question pertains to the following part of the Tracula config file: *Step7.3: Specifying Number Of low-b Images* The last step to set up if not using original DICOMs would be to specify the number of low-b images with the following variable: set nb0 = *No. of low-b images* Thank you in advance for your help.
