SEER*Prep 2.4.0
Released July 2007

The SEER*Prep software converts ASCII text data files to the SEER*Stat database format, allowing you to analyze your cancer data using SEER*Stat. SEER*Prep performs two main functions:  it converts text data to the specific binary format required by SEER*Stat, and it creates the SEER*Stat data dictionary. SEER*Stat 6.2.3 or later is required to analyze any database generated with SEER*Prep 2.4.0. If you are a new SEER*Prep user, see How to use SEER*Prep to Create a Database.

The readme.txt distributed with the software includes a description of the revisions made for this release.

SEER Incidence Site Recode and SEER Cause of Death Recode describe current and historical SEER*Prep algorithms related to these variables.

* NAACCR 10.1 and 9.1, and SEER 250 file formats are no longer updated or distributed with SEER*Prep. If you must continue to use them, there is no need to upgrade to the latest version. If you are currently using the NAACCR 10.1 format, it will be easy to move to 11.1. NAACCR 11.1 is similar but has more derived fields.
