EasyMorph can run transformations in several ways:
Auto-run mode controls whether EasyMorph runs transformations automatically, or they should be run manually. When Auto-run is on, EasyMorph attempts to automatically calculate all not calculated transformations when the project is modified. In this mode transformations are calculated in the background, without blocking the user interface. Tables and charts are updated as soon as they are calculated. If the project was modified while background calculation was running, the calculation silently restarts.
Note that export transformations are not calculated automatically. They are considered side-effect transformations because they modify data outside EasyMorph. Such transformations should be run manually, even if Auto-run is on. Other side effect transformations are Run Program and Iterate Program.
You can switch Auto-run on and off from the Main toolbar. To stop running background calculation switch Auto-run off. If you switch Auto-run on this will trigger background calculation again.
When Auto-run is off or some transformations are not calculated (e.g. export transformations) you can calculate them by pressing "Run project" button, or F5.
If you need to re-run all transformations in a project (e.g. because source files have changed) go to menu Project and press "Reload and run" button, or Ctrl+F5.
Sometimes you might want to control precisely which exactly tranformations are run. In this case you can instruct EasyMorph to run only up to a particular transformation (Auto-run must be off). To start calculation right-click the transformation and choose "Calculate" from the menu, or simply Ctrl+click the transformation.
Hint: For convenience, switch off Auto-run in projects with heavy calculations.
To preserve consistency of calculations EasyMorph intelligently discards transformation results when one of the following happens:
Discarded are only results of transformations that are affected by the change, the rest remain intact. For instance, when an expression in a transformation is modified, only results of this transformation and all transofrmations that follow (depend on) it are discarded. Results of preceding and independent transformations are not discarded.
Also, when a parameter changes, discarded are results of transformations that are using the parameter (or a parameter that was calculated using the parameter), or are dependent on a transformation affected by the parameter change.
To discard a result of transformation manually (e.g. if you want to reload a source file), right-click the transformation and choose "Discard result" from the menu. If Auto-run is on EasyMorph will automatically re-calculate the transformation and all transformations that depend on it.
Automatic recalculation of transformations after changes is especially useful for data analysis, because you can add, delete and modify transformations on the fly, and EasyMorph will instantly update charts and tables.
If errors occur during running transformations in Auto-run mode the error counter will appear in the status bar. Clicking the counter opens the list of errors. Double-clicking an error message in the list will bring you to the transformation where the error occured.
After errors are corrected, EasyMorph continues running transformations from where it stopped.
To run a project from the command line run morph.exe with /c as shown below:
In case of project errors a log file is created next to the project file, with the same name. Application (system) errors are written into EasyMorph.log in the same folder as morph.exe (by default it's AppData\Local\EasyMorph).
EasyMorph projects can be scheduled for execution with the help of EasyMorph Scheduler. Scheduling requires the Professional edition or Plus edition with the Command Line Mode option.
