Automating SPM99 Analyses

SPM 99 PET analyses can be automated using the CBU CSV modfications to the standard SPM statistical design.

Download this file attachment:cbu_csv99_ui.m, put it somewhere in your Matlab run path, and run it from the Matlab command window:

>> cbu_csv99_ui

This utility is a modified version of the SPM99 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 SPM99 to read from this file. If you create a design in the standard point-click-type interface, a re-usable text file named design.csv 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.

Documentation is in attachment:details99.txt.

Let me know if you have any problems or comments.
