Document Logs
Any changes made or actions performed on a protocol or image file generate a
document log documenting each change or action. This log is created as soon as
the protocol or scan file is created. Protocols are updated when the protocol is
saved or run. If you make changes to a file and save it as a new file, regardless of
whether you are in secure mode, the document log is preserved in the new file. If
you are in secure mode, the signature of the previous file is noted as part of the
document log.
Note: When a protocol is run, its log entries are copied to the resulting image
file.
All major actions and changes are audited (generate a document log). Examples of
auditable actions include:
 Signing a file
 Changing protocol settings
 Changing the image, for example, by cropping or rotating it
 Modifying the analysis, for example, changing the lanes and bands, or
adding or editing annotation to the images
Minor changes that affect only the display are not audited, such as:
 Selecting different columns in the Analysis Table
 Changing the display options in Lane Profile
 Annotating or labeling the image using Annotation Tools
Each change you make to a signed protocol or image file must be documented in
the Reason for Change dialog box.
