Gabriel,

Running mri_segstats will not cause any trouble, it just reads files, and doesnt modify anything.

You can run v4.2.0 on your subjects manually segmented with v4.0.5, that is, you can safely run:

recon-all -s subj -all

and it will keep and use all your edits. Only when the -clean flag is included are edits deleted.

Dear freesurfers: I have two questions:

1. I have FS v4.0.5 and i've downloaded the new mri_segstats to

calculate the eTIV, this new calculation may cause any trouble in my group of manual segmented subjects?

2. I have 60 subjects manual segmentated on FreeSrufer 4.0.5, i want

to know if i run the recon2 or recon3 in the new FS 4.2.0, will have any problem?

the diferences between versions can cause any trouble with the analisis because imcompability or something?

Regards Gabriel
