I've been struggling a bit with conversion of strings to structures (mainly smiles) for viewing in Knime - when having a dynamic number of columns.
Tried using looping, but haven't managed so far (e.g. even when I managed to loop around the number of columns, the columns end up all in one column only). I am sure though there is a solution.
Even if you don't have dynamic number of columns, multiple ones mean combining multiple type cast nodes in a row. Doable of course, but slighly annoying.
What would be simpler - and thus a request for one or any of the nodes that handle structures, be it Molecule Type Case; Open Babel; ERL String to Molecule; Indigo, whoever thinks it is a good idea or has time & resources:
Add a column selection to the node, so that one can select multiple ones at once, use variables, etc (as in Column Auto Type Cast).
Thank you for reading.
