About Grappa: display version information of Alida/Grappa
Alida supports two categories of operators, i.e., STANDARD operators and operators mainly dedicated to direct APPLICATION. The latter ones are well-suited to be used by non-expert users. Other operators often require expert knowledge.
By saving a workflow currently two files are written to disk, one containing the information about the nodes and their configuration, and one storing graphical information regarding the current workflow layout. Both are required to load a workflow again. The first one has the extension .awf, the latter one the extension .awf.gui.
The most important functions for workflow and node handling in Grappa are also accessible via keyboard shortcuts. Currently the following shortcuts are implemented:
Ctrl-N : open a new, empty workflow in a new tab
Ctrl-U : rename the active workflow
Ctrl-W : close the active workflow
Ctrl-S : save the active workflow to disk
Ctrl-L : load a workflow from disk into a new tab
Ctrl-A : run the complete workflow
Ctrl-P : open the configuration frames of all selected nodes in the active workflow
Ctrl-X : delete all selected nodes in the active workflow
