Just checked mris_euler_number, holes are calculated from euler number: holes
= 1-eno/2

Hi Melissa
mris_euler_number
writes out a bunch of stuff, including the Euler number:
mris_euler_number ~/links/subjects/bruce.dev/surf/lh.orig.nofix
euler # = v-e+f = 2g-2: 154526 - 463668 + 309112 = -30 --> 16 holes
F =2V-4: 309112 != 309052-4 (-64)
2E=3F:9273
