Hi, freesurfers I have two questions: 1- Is there a way to use QDEC to analyze data from hippocampal subfields created by recon-all -s subj -hippo-subfields? That is, I know I can manually put data from posterior* files when making the FSGD file but it would be great if I could import it like I do from aseg.stats.
when you say you want analyze the hippo subfields in QDEC, do you mean you want to include them as regressors?If so, you will need to add them to your QDEC table. BTW, QDEC does not needan FSGD file.
2- Assuming all data from my subjects are already are already in the FSGD, I understand I can select cortical thickness or volume as dependent variable and inspect the correlations between cortical thickness and age, for example. But I could not find how to define a hippocampal subfield volume as a dependent variable. Is that possible? This way I could display correlations between a subfield volume and age or gender.
I have not used the hippo subfields yet, and I'm embarrassed to say that I don't know what exactly it outputs. If there is a stats file there, you can run asegstats2table to create a table file, then use the table as input to mri_glmfit (use the --table option). doug
Thank you, Marcos
