= Automating SPM5 Analyses = SPM5 PET analyses can be automated using the CBU CSV modfications to the legacy SPM statistical design interface {{{spm_spm_ui.m}} which is included in the {{{SPM5}}} distribution. Download the file [[attachment:cbu_csv5_ui.m]], put it somewhere in your Matlab run path, and run it from the Matlab command window: {{{ >> cbu_csv5_ui }}} This utility is a modified version of the SPM5 legacy interface (spm_spm_ui.m) inherited from SPM99 and SPM2, for specifying the design and image file locations in a PET study. The utility automates the specification of factors (group, subject, condition, replicate) and covariates, and selection of the image datasets, 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 CbuCsv5Details. Let me know if you have any problems or comments. Updated by IanNimmoSmith on 5 September 2006.
