This page details the file format when ROI statistics are written to disk by the ROI Toolkit of Jim.
A stats file is a plain text file, consisting of a header line, followed by list of ROI statistics, one line for each ROI. The header and statistics present depend on which of the check boxes are selected for writing in the ROI Toolkit frame.
If all statistics are selected for writing, then the header line consists of the comment character (#) followed by eight headings as below:
# Annotation Slice Area Mean StdDev Min Max Length
If extended statistics are shown,
then another three headings may also be shown:

The annotation string is written without quotation, and all white space in the annotation entered by the user is removed. Numerical values are written either in integer format or in floating point format. Only line ROIs have a defined length; the characters "N/A" (not applicable) will appear in the length column for all other ROI types.
