[Mristudio-users] b-matrix from dicom header and from techs

[Rajagopalan, Venkateswaran]

Thanks very much Dr.Mori
 
I'm wondering why you are using NIFTI, not the original DICOM (or MOSAIC) files. If you could orient us in this respect, we may put some effort in supporting header structures other than DICOM in terms of the gradient table information. 

I am using FSL for eddy current/motion correction and rotating bvecs after eddy current/motion correction. Since FSLview is quite handy to look at the quality of registration and even for some of post processed DTI images I am used to FSL. FSL recommends NIFTI format i am using NIFTI. If you can support NIFTI it would be great.
 
Last one When i try to run DTIstudio-latest-x86.exe it gives me the following error "This application failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem". Any help on this would be greatly appreciated.


Is it a reproducible problem?

Xin helped me with this, i didn't know that i need to install visual studio/C++ which was available in MRI studio website. Sorry about that. Now problem solved.
 
Thanks
 
Venkateswaran

Hi Venkateswaran,

I think Hangyi can answer some of the questions, but few comments here;




	2) When i use dcm2nii to extract gradient table information for these older software versions it is mentioned by Chris Rorden that he appropriately rotates these gradient tables to conform to NIFTI format (since dicom and NIFTI coordinates are different).  I am using FSL for eddy/motion correction and also to rotate bvec after eddy/motion correction. I however convert NIFTI to Analyze format and then to dti "raw" format and do tensor calculation so i am wondering whether this "raw"format has same coordinates as NIFTI.
	


I believe the coordinate definition is related to the header, but the "raw" format doesn't have header. So, except for the order of the matrix, there should not be difference between NIFTI and raw for the image matrix section.
 



	3) Do you have  an option in DTIstudio to open NIFTI files.
	


The current DtiStudio can read NIFTI but I don't think it can extract gradient information in NIFTI.
I'm wondering why you are using NIFTI, not the original DICOM (or MOSAIC) files. If you could orient us in this respect, we may put some effort in supporting header structures other than DICOM in terms of the gradient table information. 



	4) Last one When i try to run DTIstudio-latest-x86.exe it gives me the following error "This application failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem". Any help on this would be greatly appreciated.
