RE: bvals and bvecs for the diffusion MRI data

aaron_carass — Tue, 29 Aug 2023 2:05:38 GMT

For each subject that we provide DWI data, there is a file with subjects ID followed by either `DRBUDDI_up_final.bmtxt' or `DRBUDDI_final.bmtxt'. These files can be used to generate the bval and bvec files using the DIFFPREP command from the TORTOISE software.
 
TORTOISE can be downloaded from https://tortoise.nibib.nih.gov/tortoise/

bvals and bvecs for the diffusion MRI data

Adnan Hirad — Thu, 04 May 2023 7:16:25 GMT

Hi -

I hope this email finds you well. We are trying to use the U01 diffusion data and generate metrics other than the ones provided; unfortunately there are no bvec or bvals in th DWI data folder. Could you please share with us these files? Please, let me know if there is anything I can clarify!

Thank you so much -
Adnan

Obtaining wave motion from total displacement field

abhiawasthi — Tue, 30 Aug 2022 18:24:53 GMT

Hello everyone,

I just downloaded the MRE data wherein the complex total displacement field data ([color=#ff0000]wave motion + rigid body motion[/color]) is provided. In order to further use the displacement data for stiffness reconstruction, I need to separate the [color=#ff0000]wave motion[/color] from the rigid body motion.

However, I could not find any data corresponding to the rigid body motion. Could anyone please tell me how I can get the wave motion data?

Any help in this regard would be highly appreciated.

Thank you
Abhilash
