Issue I231 [feature,partiallyresolved] Allow splitting data recording output into multiple files. The following feature requires SIMION version 8.1 beta (or 8.0.5-TEST34-TEST or above running in early access mode - see Issue I421). Data recording output can now be split into different files, one per re-run. In the Data Recording "Output File" field, include the variable substitution "$(ion_run)" anywhere in the output file name. Alternately, just click just click the "separate file per rerun" check box, which will add this variable automatically. For example, out-$(ion_run).txt If you do that in the "tune" example, which does 15 re-runs, it will output 15 files: out-1.txt, out-2.txt, ..., out-15.txt Beware that data recording is disabled if the "Rerun" checkbox is enabled upon the start of a Run (Issue I489).
