Thanks, Yujing.

Do you know why the output of mri_vol2vol would be different if using the .lta vs the .dat file? And, if the .dat file was verified/modified using tkregister2, would the .lta file also be updated accordingly?

Thanks

Hi Corinna,

Here is an explanation of register.dat - MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://surfer.nmr.mgh.harvard.edu/fswiki/RegisterDat

You can use lta_convert to convert it to .lta - MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://ftp.nmr.mgh.harvard.edu/pub/docs/html/lta_convert.help.xml.html

Best,

External Email - Use Caution

Hi all,

Can someone please explain the difference between .lta and .dat and why the registration looks different using the two file types?

If bbregister outputs were already checked and edited (if needed) using the .dat file, is there a way to convert it to .lta?

Thanks

Corinna
