the 'generate stats data tables' button in the Subjects tab will do this. see the section 'Stats Data Import' in the tutorial: https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/QdecGroupAnalysis which is copied here:

It is possible to import the aseg and aparc data from the FreeSurfer-processed group data. To do so, press the 'Generate Stats Data Tables' button. This will run the FreeSurfer utilities asegstats2table and aparcstats2table on your group data. Upon completion (you should see the progress in the terminal screen), then the 'Generate Stats Data Tables' button becomes a menu-selection list. Within that menu, you can select 'aseg.volume'. Upon doing so, the volumetric data for various subcortical structures are displayed. You could choose for example 'Left-Lateral-Ventricle', then click 'Add Selection to Data Table'. Upon doing so, it will appear in the 'Discrete and Continuous Factors' display of the 'Data Table View'. 'Left-Lateral-Ventricle' is now available as a possible factor in your analysis ('Left-Hippocampus' and 'Right-Hippocampus' were imported from aseg.volume in this manner). If you select 'Left-Lateral-Ventricle' in the 'Data Table View', then the volumetric data for all the subjects is plotted. You can look for patterns or outliers. If you suspect an outlier, right-click on that point in the scatter-plot. You can then either exclude that subject, or examine it in tkmedit or tksurfer, to check for possible problems in the original scan data. Lastly, you can save this newly imported data (in this case, 'Left-Lateral-Ventricle') to your qdec.table.dat file by selecting 'Save Data Table' from the File menu (but dont do this for the tutorial).

Hi freesurfers

Do anyone know if it's possible to automatically enter in the QDEC table the gray matter volume of every subject in the study, to avoid entering this item manually for each one ?

Best regards.
