Hello Doug and other experts:


I have done QDEC analysis between two groups (healthy controls vs disease) and obtained different .mgh and .annot files. I got one big cluster covering most part of the brain. I wanted to extract the number of vertices for Yeo's 7 Networks in that big cluster and therefore I ran this:


mri_segstats --i cache.th30.pos.sig.masked.mgh --annot fsaverage rh Yeo2011_7Networks_N1000 --excludeid 0 --sum network_param.dat

The result was:

Col Headers  Index SegId NVertices Area_mm2 StructName Mean StdDev Min Max Range  
  1   1     22519    14950.0  7Networks_1                        1.4816     1.8126     0.0000     3.6990     3.6990 
  2   2     30207    12514.7  7Networks_2                        2.6658     1.6596     0.0000     3.6990     3.6990 
  3   3     17604     8224.3  7Networks_3                        2.6278     1.6778     0.0000     3.6990     3.6990 
  4   4     19402     8357.2  7Networks_4                        3.3453     1.0877     0.0000     3.6990     3.6990 
  5   5     11614     6205.0  7Networks_5                        2.1434     1.7750     0.0000     3.6990     3.6990 
  6   6     22330    12170.7  7Networks_6                        2.6315     1.6761     0.0000     3.6990     3.6990 
  7   7     26056    13826.2  7Networks_7                        3.0249     1.4229     0.0000     3.6990     3.6990 

I ran the same code for different --i (input) .mgh files and everytime the NVertices were the same, which means this is not the one I am looking for. 

Can you please help me in getting the number of vertices of Yeo's each network that fall in that big cluster?

Thanks.

Anwar
