[Mristudio-users] btable for Siemens DICOM dataset

[Deepa Krishnaswamy]

Hi,
I changed the format, so that there is a comma before the bvalue, and I did
what you recommended for loading the btable. I don't think there is a
syntax error because I generated the btable from another program; there are
definitely 515 lines. I also put in a value of 1 for optional bvalue. I'm
still getting the error message where only 493 images are found.
Thanks,

Deepa
