String splitting

I am having trouble splitting a string of characters into component pieces in new 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  -  but that didnt work in my hands.  any ideas what i might be doing wrong here?



I think you could try to modify the string using the "String Replace" node with the regex "([A-Z]{1})", "$1|" as substitution and "...all occurrences" on.

this will then allow you to split the string using the character "|" with the "Cell Slitter" node
