Issue I489 [70,80,partly-resolved] Data recording disabled if rerun enabled at Fly'm start. The SIMION 7.0/8.0 manuals say (e.g. p. 8-14 SIMION 8.0 manual) "3. Third, if data recording to a file is active, SIMION will take note of the status of the Rerun at the instant when the Fly'm button is pressed to start flying ions. If Rerun is checked (at that instant) then no recorded data will be sent to the user designated data record file during the entire Fly'm. However, recorded data will always appear on the Data Monitoring Screen (if and when displayed)." This is specified behavior, but should it be changed? Is the existing behavior at all useful? Why is it defined explicitly this way? (TODO-check). Note: Use of both data recording and reruns is useful, such as for a lens tuning example that also data records. In that case, the program itself will likely enable the reruns just after the Fly'm has started and terminate the reruns just before the end of the tune. The data recording will occur provided the user does not have reruns enabled prior to clicking Fly'm. However, if the user prematurely terminates the Fly'm, then the reruns option will remain active after the Fly'm is done, and the user MUST then manually disable rerurns before re-attempting another Fly'm or otherwise there will be no data recording. This may be error prone. Perhaps SIMION should reset the rerun state to what it was prior to the start of the Fly'm. That is what SIMION does concerning adjustable variables. Similar things might need to be said concerning Retain and View (trajectories) options. Some might temporarily enable the rerun option to see ions reflying, such as when tuning adjustable variables. In such case, even if the system normally has data recording enabled, you might not want large amount of data from many reruns to fill the disk.
