Standing for GenePix Pro Results (GPR). This format is somewhat volatile since it changes with changing GenePix software. GPR files are all valid Axon Text File (ATF) files, which means that: 1. they are tab delimited text files with a single row of column titles. 2. The file header dimensions are described in the second line of the file.
GPR files contain general information about image acquisition and analysis, as well as the data extracted from each individual feature. Any user-defined feature data contained in a GAL file read by GenePix Pro 4.1 will be included in the output GPR file. As of GenePix Pro version 18.104.22.168, the GPR version number is 3.0.
