External Email - Use Caution

Hello,

I used the longitudinal HippocampalSubfieldsAndNucleiOfAmygdala https://surfer.nmr.mgh.harvard.edu/fswiki/HippocampalSubfieldsAndNucleiOfAmygdala?action=fullsearch&context=180&value=linkto%3A%22HippocampalSubfieldsAndNucleiOfAmygdala%22 pipeline to create subject-specific hippocampal ROI's for a paper I am preparing for submission. I would like to know what the best way to cite this technique is.

This is what I currently have in my methods section.

Subjects T1-weighted anatomical images were processed with the FreeSurfer image analysis suite (http://surfer.nmr.mgh.harvard.edu/, version 6.0) and Automated hippocampal subfield segmentation was performed for each subjects T1 weighted image using the Freesurfer longitudinal hippocampal subfield segmentation program(Iglesias et al., 2015, 2016).

Do I need to cite my use of the development version? And if so how is the best way to go about doing this?
