= Automating spm99 Analyses = SPM 99 PET analyses can be automated using the CBU CSV modfications to the standard SPM statistical design. Download this file {{{ }}} for our version of spm 99b with local edits. This means that matlab will find my edited version of the file [http://imaging.mrc-cbu.cam.ac.uk/downloads/Csv/spm_spm_ui.m spm_spm_ui.m]. To install this feature outside the CBU, merely download the spm_spm_ui.m file from the link above, and save it into some directory on your matlab path that is in front of the SPM 99b distribution, and start SPM.The facility is a modified version of the SPM99b interface (spm_spm_ui.m) for specifying the design and image file locations in a PET study. This automates the stages, after design type selection, of specifying group, subject, condition, replicate and covariate information by preparing a text file in advance and then telling SPM99b to read from this file. If you create a design in the standard point-click-type interface, a re-usable text file is created in the requisite format. I have found this facility useful for running multiple 'what if' analyses - seeing what the effect is of dropping a subject, or a condition, or adding an extra covariate, etc. etc., at the cost of a few edits to a text file. An equivalent version for the SPM99b interface (spm_spm_fmri_ui.m) for fMRI time series studies is under development. With luck the planned upgrade to SPM99 will incorporate equivalent features. However, in the mean time, you may find this a useful time saving and accuracy enhancing addition.
