You can get the WM from our white matter segmentation (wmparc.mgz and stats table wmparc.stats). You'd need to pick the cortical labels that you want to define as the "frontal lobes". You should create a binary mask with mri_binarize, passing the indices of the segments you want to use with the --match option, then load the mask in tkmedit to see whether it is what you expect. You can do a similar thing with the gray matter, but you can get the volumes from the ?h.aparc.astats
