Hi Natalia,

the images in 5.0 are not in the same voxel space across time. Probably that is what's causing your problems. In 5.1 they are all resampled and processed in the subjects' template space. So you cannot simply open stuff on top of each other with 5.0 data. However, surfaces are in vertex correspondence even in 5.0 and therefore I expect long_mris_slopes to work on 5.0 data. long_stats_slopes should also work with 5.0 data as the stats files should not have changed too much, but who knows.

Best, Martin

Hi Martin,

Thanks for the reply. I updated to 5.1 and loaded the -base and -long processed data. The -base for two timepoints look fine, but the Time1sub1.long.Templatesub1 & Time2sub1.long.Templatesub1 are not well aligned. (p.s screen shot in the attachment) I checked both the pial and white surfaces, as well as the norm volume between time points. It seems like they are not well registered. I used the mri_convert from DICOM to mgz. Is there a way to solve this?

Thank you

Hi Natalia, I have never tried it, but don't see a reason why it should not work. Just try it out.

Dear list,

I have a question about the longitudinal stream´s version. I used Freesurfer 4.5 and followed the longitudinal tutorials (the tutorials "before" June 2011) for my data. I saw on the updated version, there are scripts which can do the post-process longitudinal data, like long_mris_slopes, long_stats_slopes, long_qdec_table. Can I use these scripts to do the stats even though I used version 4.5 for the longitudinal process?

Thanks for the help
