SEER-Medicare: File Sizes & Distribution

Data will be sent to investigators on thumb drives.

The data files will be encrypted using SecureDoc and password-protected. The data files will also be compressed using the GZIP compression utility. Programs will be made available to decrypt and unzip the files onto the user's PC in the directory that the user specifies. The PC must be equipped with Windows NT, Windows 95 or later. GUNZIP is necessary to unzip the files if using a UNIX or Linux machine.

The following table provides some examples from recent productions. The files are compressed before they are written to the thumb drives, however, the file sizes provided are for the files in their non-compressed format. The table shows the estimated size of files in gigabytes and the number of thumb drives for one major cancer site (colorectal) and for four major cancer sites combined (breast, colorectal, lung and prostate). Also shown are estimates and media requirements for the 5% all cancer and non-cancer databases.
