Hello,
Im wondering if there is an update regarding etiv differences between recon all
and using sclimbic. I want to divide the volumes extracted from using sclimbic
on t1s by etiv. Im not sure given the discrepancy if I should use etiv
extracted from recon all command or from sclimbic.
Thanks,
Miriam

Hello,
I just wanted to follow up about etiv, if you had the chance to look into if
your recon all vs sclimbic also does simithing similar on the subjs i sent?
I am also attaching another graph that depicts the difference between etivs
extracted from sclimbic and from recon all.

Thanks for all your help,
Miriam

Hello,
Attached are a few subjects, where YA denotes younger adults and OA older
adults. I also included the stats file when I run sclimbic for reference.
Please let me know if this mode of transfer works.
Thank you,
Miriam
P.S. I also sent a previous email regarding etiv values "etiv value differs if
using recon all vs freesurfer dev". Are you able to also see if your sclimbic
etiv values differ much from recon all? For example, sub1221084 etiv greatly
differs between sclimbic, old recon all, and new recon all.

Hello,
Thank you for your quick response!
I can certainly share a few participants data with you but I would prefer not
to share with the entire mailing list if possible. If so, should I attach it to
this email?
I could send you more than one if you prefer.
Thank you,
Miriam

Can you send us a sample case?

Nothing strange about them.
They’re T1w scans 1x1x1mm3

Have you looked at the input volume to see if there is anything strange about
them? What kind of scans are you passing to it? What is the resolution?

Hello,
I noticed 20 out of ~240 subjects left basal forebrain volumes were not picked
up after running ScLimbic. These are healthy adults and their scans look good.
Also, I noticed often when this occurs NAcc is also 0 or other regions.
I am concerned if there is a systematic issue with left volumes ending up
smaller than they should relative to right.
Thanks,
Miriam
