ACS SASSI's Interfaces and modules use a number of different types of files. This section is intended to list all of these files and explain the format of the ACSII file formats to the user. This section will also list the binary file used in SASSI and provide the user a list of the Programs / Modules and types of analysis that require the binary file. Many of the files in the table are listed by a default extension. Changing the extension will not change the contents of the file or the programs or modules ability to read the file.
