Data File Formats and Trace Viewer Software

The .pdf files of the electropherogram traces, which show the fluorescent intensity of the dye-labeled fragments, the resulting .seq files (sequences) and AB1 files (raw data) will be emailed to both the requestor and the principal investigator. If the requestor or principal investigator would like to open the AB1 raw data files, trace viewer software is required to do so. We recommend ABI's Sequence Scanner Software v1.0 which is a free download and can be found at the following link:

This software is only available for Windows operating systems.

For other platforms we recommend the following free trace viewer downloads: Finch TV which is available for Windows, MacOSX or UNIX can be found at the following link:
