Hi Yujing,

Thanks again for your quick response. 

For src image, do you mean the file that I used to generate the original register.dat file?
For instance, the register.dat file was produced by running dt_recon (using input of dti.nii.gz). 

Is this dti.nii.gz for file I should use for correct conversion to reg.lta?

Thank you!

Hi Yujing, 

 

I really appreciate your quick response. 

 

The following is the error I get when I try to perform this:

 

Mirsols-MacBook-Pro:dtrecon mirsolchoi$ lta_convert --inreg register.dat --outreg reg.lta

7.4.1

 

--inreg: register.dat input TK REG transform.

--outreg: reg.lta output reg.dat matrix.

INFO: This REGISTER_DAT transform is valid only for volumes between  COR types with c_(r,a,s) = 0.

error: corRead(): can't open file /Users/mirsolchoi/Desktop/subjects/sub-001/dtrecon/COR-.info

ERROR readREG: cannot read src MRI

Mirsols-MacBook-Pro:dtrecon mirsolchoi$ 

 

 

Is there an additional file I need to complete this process?

 

Thank you so much for your time.

You can try lta_convert.

 

Best,

Hello there, 


I am wondering if there is a way to convert register.dat file produced from dt_recon to reg.lta. I need a reg.lta file that contains registration between the DTI data and processed (recon-all) T1 data. 

 

I have tried to perform bbregister, but the alignment is completely off.

 

Thank you so much for your time!

Mirsol
