View intermediate results of active runs

When editing and running models, Pirana can automatically backup all versions of controlstreams and result files. When this Auto-backup models & results option is activated in the Settings dialog (see General settings), intermediate versions of models and results are saved in the pirana_backup subdirectory of the active project, every time a model is changed, or when a new results files is found.

During a run, intermediate results can be accessed via the icon in the toolbar, or by selecting the View > Intermediate results of active runs menu option. In the Progress dialog, there is an Intermediate results tab. Details of the run and (if applicable) parameter estimates can be reviewed.

By clicking on a run in the list, Pirana will parse the intermediate files and show the intermediate parameter estimates in the table and the plot. In the plot, you can choose to show either the gradients (if a gradient method is used), the intermediate estimates, or the objective function value (OFV). Make sure that you specify PRINT=1 and MSFO=xxxxx in the $ESTIMATION record, to be able to obtain regularly updated intermediate estimates. From the submenu, signals can be sent to currently running model processes, such as stop and next iteration.

Click Export as CSV or Export as LaTeX to send the intermediate results to a file.
