Automating SPM99 Analyses

SPM99 PET analyses can be automated using the CBU CSV modfications to the standard interface for setting up the required SPM statistical design.

Download the file 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 PET interface (spm_spm_ui.m) for specifying the design and image file locations in a PET study.

The utility automates the stages 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. Alternatively, you can use the utility to create a re-usable text file named design.csv in the requisite format if you use it create a design in the standard point-click-type interface.

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 CbuCsv99Details.

Let me know if you have any problems or comments.
