I am having trouble splitting a string of characters into component pieces in new columns....it is a simplified string of atom types e.g. CCNCCNCCCCCNNCCO, and all I want to do is create a new column to contain each character.
I tried following the advice here - http://tech.knime.org/forum/knime-users/split-string-sequence-with-regex-split but that didnt work in my hands. any ideas what i might be doing wrong here?
