Hi Doug,

Thanks! I realize now I didn't explain myself properly.

I need one single R value for the correlation analysis I made, similarly to when I correlate two variables with Pearson's R in a statistical package.

I have a referee asking me to put it on a table with the freesurfer results. Is there a way to get a single average R value from the pcc.mgh file?

Thank you so much!

Each vertex is a correlation value.

Thanks Doug!

I have version 6 and got a pcc.mgh file.

How can I get a correlation R value from this file?

Thanks again

if you are using version 6, then it should have produced a file called 
pcc.mgh. This the partial pearson correlation coef.

Dear Freesurfers,

I made some correlations between cortical thickness and age in qdec.

Is it possible to get the correlation coefficient value of this analysis?

I just need to put it in a table with the significant results.

Thank you so much!
