“ep2d_diff” is the Siemens product diffusion sequence, so MB was probably not used. You should be able to confirm from the TR as well. My only hesitation (and why I said “probably”) is that I’m not sure if the product SMS option that Siemens just released with VE11C is implemented into their standard “ep2d_diff” sequence. If so, discerning whether MB was used in those Siemens product sequences will require probing of a different field (which I’m not familiar with currently). Can’t you just check with whomever provided the data…? cheers, -MH -- Michael Harms, Ph.D. ----------------------------------------------------------- Conte Center for the Neuroscience of Mental Disorders Washington University School of Medicine Department of Psychiatry, Box 8134 660 South Euclid Ave. Tel: 314-747-6173 St. Louis, MO 63110 Email: [log in to unmask] From: FSL - FMRIB's Software Library <[log in to unmask]<mailto:[log in to unmask]>> on behalf of Martin Juneja <[log in to unmask]<mailto:[log in to unmask]>> Reply-To: FSL - FMRIB's Software Library <[log in to unmask]<mailto:[log in to unmask]>> Date: Wednesday, November 30, 2016 at 10:48 AM To: FSL - FMRIB's Software Library <[log in to unmask]<mailto:[log in to unmask]>> Subject: Re: [FSL] DTI Multi band sequence? Hi, When I run these commands, it gives following outputs: $ strings IM-0001-0001-0001.dcm | grep -i tSequenceFileName tSequenceFileName= ""%SiemensSeq%\ep2d_diff"" $ strings IM-0001-0001-0001.dcm | grep -i sWipMemBlock.tFree $ This gives no output and no error. $ strings IM-0001-0001-0001.dcm | grep -i "sWipMemBlock.alFree\[13\]" $ This also gives no output and no error. Does that mean this data set is not multi band ? Thanks. On Wed, Nov 30, 2016 at 9:13 AM, Mahmoud <[log in to unmask]<mailto:[log in to unmask]>> wrote: Dear Michael, Thanks for your clarification.

In all the more recent CMRR sequences, you can find the multi-band factor in the "sWipMemBlock.alFree[13]” entry (where “more recent” corresponds to a sWipMemBlock.alFree[10] value >= 4). You also can get some specifics on the sequence version in the “tSequenceFileName” and “sWipMemBlock.tFree” fields. e.g., in the example below, we were using the “cmrr_mbep2d_bold” sequence, compiled “Nov 19 2014”, and we ran it using an MB factor of 8.
