Newbies MaSchmid Posted March 16, 2011 Newbies Share Posted March 16, 2011 Dear All, I was wondering if it is possible to count how often a particular character (i.e. 'A') occurs in a string (i.e 'AGCTATGCA). In this example the answer should be 3 (obviously). Now doing this using a script is easy, but I can't figure out how to do it in a field calculation. What I really would like to do is to be able to enter a string (its a DNA sequence btw) in >field1< which should result in a auto-enter calculation in >field2<. The calculation requires the number of 'A's in the string in >field1<. Any suggestions? Thanks, M Link to comment Share on other sites More sharing options...
comment Posted March 16, 2011 Share Posted March 16, 2011 Try the PatternCount() function. a auto-enter calculation in >field2<. Why not use a calculation field? Link to comment Share on other sites More sharing options...
