PPM 24-bit color image that is formatted in text format. Each pixel is assigned a number from 0 to 65536 that defines the color of the pixel. Other information included in a PPM file includes the image height and width, whitespace data, and the maximum color value.

Insight II is a comprehensive graphical molecular-modeling program from Accelrys Software, Inc. In this context, a PPM file is one of the data files used by the program.
The file contains saved proton chemical shifts for use in Insight II.
This format is associated with the Linux and Unix versions of Insight II and is a specialized, program-specific data format.
Open the file with Insight II on a compatible Linux or Unix system. Use Insight II's file-opening or import commands to load the saved proton chemical-shift data.
A PPM file is not normally converted to a general-purpose format because it stores Insight II-specific proton chemical-shift data. Use Insight II's own import or export functions when the data must be exchanged with another supported workflow.
