I just installed Knime 3.1.2 on Mac OS X El Capitan (10.11.4) with all extensions including indigo 2. But it looks like all chemoinfromatics analytics using indigo extensions is not working. I always get the attached error message regarding missing indigo to molecules or molecules to indigo.
The problem seems to resiste whatever I try to do. For example, uninstall and reinstall extensions.
Can you help me, I need to use knime for some data mining shortly.
To understand why it happend, please, look at this announcement where it's explained why all these converting from and to Indigo type nodes were excluded. The converters are still available in KNIME 2.12 extension. Also it's under considerartion now to put them back marked as Deprecated. We will let our users know if decide to turn them back.
