From: LMH medchem Date: 2013-01-11T04:55:23+09:00 Subject: Re: adding variable values to output (to file) I also forgot to mention that I am wondering if it would be easier to already have a column in the input file named class with some default value and to change the default value to something else, as opposed to trying to shoehorn in additional columns. Any thoughts on that??? LMHmedchem -- Posted via http://www.ruby-forum.com/.
