Dear Dough,
Is samseg2recon run by default when we run just samseg command? After samseg is completed it displays towards the end samseg2recon run time in sec and hours, right before computation time of samseg as below. If it is called by samseg command itself there would be no need to run samseg2recon separately after samseg command right unless it is doing something in addition?

it is not run by default.
I had ran few subjects with samseg from Freesurfer dev version in Oct of 2019 and compared it with samseg version from Freesurfer v7.1.0 and realized that some file names are different. Samseg from dev version I ran in 2019 created file t1w_biasCorrected.nii, t1w_biasField.nii, t1w_crispSegmentation.nii names under saubject/mri/samseg directory and Freesurfer v7.1.0 creates mode01_bias_corrected.mgz, mode01_bias_field.mgz, seg.mgz files. I assume these files should be comparable across these two versions right? Also, I do not see seg.stats file when I ran with dev version in 2019. Which stat file am I suppose to consider in lieu of seg.stats file when I ran with 2019 dev version?
Yes, a lot of file names changed. You should look at the seg.stats file
Besides, when we ran samseg in 2019 we had used mri/T1.mgz file as an input. Will this be a problem based on your suggestion in https://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg65310.html
Thank you,
Sneha

In theory it is possible, though I don't know if it is better or worse. You can run samseg, then run samseg2recon (this creates a folder that looks like it was created by recon-all), then run subfields on that folder

* External Email - Use Caution * Dear experts, I want to revisit if anyone has ran subfield analysis just by running samseg? If it is possible is it as reliable as from running regular routine with “-all” recon-all flag?
