Hi all,
I have a question related to the results of fixelcfestats.
I would like to correlate FD, FC and FDC with behaviour. I run fixelcfestats with the following design matrix:
Handedness, Age, Total intracranial volume, behavioural variable, column of 1s
and the following contrasts (one analysis for each contrast):
0 0 0 1 0 and 0 0 0 -1 0
I obtain my results, and so far everything is alright.
Now I would like to extract the actual FD, FC and FDC in numbers, and display it in a scatter plot with the typical regression line on it. I use mrdump to extract the values from each single subject like this:
mrdump -mask myROI.mif FD_SubX_input.mif FD_SubX_output.txt
where FD_SubX_input.mif is the file of each single subject in the folder fd_smooth created during the preprocessing.
Now, the problem is that fixelcfestats ultimately deals with the residuals, after correcting for all nuisance regressors, but the folder fd_smooth contains the original values.
Is there a way to export the residuals as numbers?
Thank you very much, and have a nice week end,
Giuseppe
