Name
["selxavg-sess"] - computes the average signal intensity maps for each condition for each individual subject.
Synopsis
["selxavg-sess"] sf <subjectfilename> df <srchdirfile> analysis <sem_assoc>
Preprocessing
mkanalysis must me run
Paradigm files placed in each bold directory
Output
This will create a subdirectory with the same name as your analysisname under the bold directory in subjects directory. There will be two volumes in this directory, one with stem h and one with stem h-offset. These are where the hemodynamic averages are stored, i.e.:
h: contains the estimated hemodynamic response at each voxel, along with the standard deviation of the residual error.
h-offset: contains a map of the mean value at each voxel.
There is also a text file called h.dat with information about the parameters used during the analysis. Future processing of this analysis will create other subdirectories under analysisname.
Description
This program computes the average signal intensity maps for each condition for each individual subject.This program separately analyzes the data in each session indicated in the sessid file, then computes the average signal intensity maps for each condition. This average data can be further processed on an individual basis and/or can be used for group analyses.
