7 years ago Commit e2236e8 adds this capability. There are two new command line options:
-output_density_filenamedefines the output current density for every iteration-output_sum_density_filenamedefines the output of the final summed current density
Some things to note:
- The format of the output is decided by the filename extension. Options are:
.asc,.asc.gz, and.amp. - There are four special strings that will be expanded at the time the file is created; these are:
{src}: The ID of the source node used for the pairwise calculation{dest}: The ID of the destination node used for the pairwise calculation{iter}: The iteration number of the pairwise calculation{time}: The time at which the file was created Optionally, you may provide a field-width specifier after the variable name to pad the number with0s to fill that width. For example, the string{iter:4}would expand to0025on iteration #25.
- Omitting
-output_density_filenamefrom your command-line options means the solution will be discarded after each iterations. Likewise, if you omit-output_sum_density_filename, the final summed current density will be discarded. There are no defaults for these options. - These new options alleviate the need for
-output_directory,-output_prefix,-output_format, and-output_final_current_only. For example, this combination of switches:-output_directory ${OUTPUT_DIRECTORY} \ -output_prefix deer_ \ -output_format asc \ -output_final_current_only 0 \Can be replaced with:
-output_density_filename "${OUTPUT_DIRECTORY}/deer_{iter:6}.asc" \ -output_sum_density_filename "${OUTPUT_DIRECTORY}/deer_final.asc" \
Example usage
-output_density_filename "${OUTPUT_DIR}/bb270_{src:5}_{dest:5}.asc.gz" \
-output_sum_density_filename "${OUTPUT_DIR}/{time}_bb270_sum_{iter}.asc" \The first switch will create a compressed ASCII grid at every iteration, with the source and destination node IDs in the filename padded to 5 digits. Some sample results look like this:
bb270_00001_00518.asc.gz
bb270_00003_00154.asc.gz
bb270_00006_00469.asc.gz
bb270_00007_00382.asc.gz
bb270_00008_00376.asc.gzThe second switch generates an uncompressed ASCII grid file when the solution is completed. The resulting filename is prefixed with the time at which the solution converged, and ends with the number of iterations it took to complete. A sample result would look like this:
1483528696_bb270_sum_2412.asc

@eduffy Instead of each pairwise solution being numbered by iteration is it possible to name each pairwise calculation based on its location so one can go back and inspect a particular set of nodes? This is probably most important for the
