Hi Colin have you tried mri_convert? We did support bshort as a format (such as it is!), although it hasn't gotten much use for years. Try something like: mri_convert file.bshort file.nii cheers Bruce On Sun, 5 Aug 2012, Colin Reveley wrote: also -  I'm assisting someone with a dti analy

also - I'm assisting someone with a dti analysis. the data I have is a martinos centre .hdr .bshort file, acquired at martinos I think, in 2005. I'm having trouble figuring out how to covert this (mainly for use with FSL) I'd like a 4d nifti ultimately (or analyse). I was thinking of writing code

You need to give it the full path to the file, eg 001/447-5-440.ima. I have a feeling that this will also fail because it's going to think that the .ima is the old siemens ima format. Let me know. Also, there's no need to put the dicoms in separate directories as freesurfer can find only those

hi gregory, to address your last question: no, tksurfer does not require both eccentricity and polar angle data to display either coordinate map by itself. as bruce wrote, the convention is that the eccentricity and polar angle data are each stored in two separate overlay or ".w" files. the ".w"

What is the nature of the complex data? Ie, what format is it in? mri_vol2surf will convert shorts, ints, and floats, single and multiple frames/timepoints, but it will not specifically handle complex. I was not aware that any format could code complex, but maybe nifti can? doug Bruce Fischl

Hi Gregory, I'l leave the mri_vol2surf to Doug, but basically we treat the components separately - one file for the real and one for the imaginary. You should convert each of them to a .w file. You can display either with a color wheel in tksurfer. Jon Polimeni is the current expert on this st

We have complex-valued volumes (retinotopic mapping data) in structural space (1,1,1mm) We'd like to convert this to a surface overlay (.w) Can mri_vol2surf handle complex data and can Freesurfer display this? (with some sort of color wheel scheme) Also, does freesurfer require both polar and e
