Boulder Laboratory for 3-Dimensional Electron Microscopy of Cells IDFPROCESS(1) IDFPROCESS(1) NAME idfprocess - do operations on and get statistics from distortion fields SYNOPSIS idfprocess [options] input_file(s) output_file DESCRIPTION Idfprocess will do several simple operations on image distortion field files: it can compute the inverse of the fields in one file, or the product or difference of fields in two files, and it can report statistics on the vectors of each distortion field. If a product or difference is taken, two input files are required, but the output file is optional. If an inverse is taken, only one input file is expected, and again the output file is optional. In either case, if no output file is specified, the program will reports statistics on the output automatically. If no operation is performed, statistics will be reported for the fields in the input file. For products and differences, if one file has one field and the other has more than one, the single field will be combined with each of the fields in the other file. If both files have more than one field, there must be the same number of fields in both files, and corresponding pairs are combined to produce the same number of fields in the output. Idfprocess uses the PIP package for input exclusively (see the manual page for pip). The following options can be specified either as command line arguments (with the -) or one per line in a command file (without the -): -in1 OR -InputFile1 File name First input file with distortion fields. If this option is not entered, the first non-option argument will be used for this input file. -in2 OR -InputFile2 File name Second input file with distortion fields. If this option is not entered and a second input file is expected, the second non-option argument will be used for this input file. -output OR -OutputFile File name Output file for processed distortion fields. If this option is not entered, the second or third non-option argument will be used for the output file, depending on whether one or two input files are required. If no output file is specified at all, then statistics will be computed. -product OR -Product Compute product of two distortion fields -difference OR -Difference Compute difference between two distortion fields -inverse OR -Inverse Compute the inverse of the distortion field -stats OR -Statistics Report mean, SD, and max of distortion vectors -second OR -SecondGrid If the grid characteristics (spacing and number of grid points) differ between the two files, convert to the second file's characteristics rather than the first. -help OR -usage Print help output -StandardInput Read parameter entries from standard input.
