[VoxBo] extracting time series data

[marina bedny]

Hi Dan,

Thanks for your response. I've replaced my character covariates with  
numbers which solved my problem. It would in fact be great if the  
averages.txt file was filled in, in the mean time, are the time  
series data out of the voxel surfer accurate (provided the glm is set  
up properly)?

Thanks,

marina
