Class Method Details

.args_to_hashes(args, replicate_postfix = "-rep") ⇒ Object

expects arguments in one of two forms. The first form is grouped by condition as shown:

condition1=file1,file2,file3... condition2=file4,file5...

The second is where each file is its own condition (1 replicate):

file1 file2 file3

Returns three ordered hashes (only ordered for ruby 1.9): 

1) Condition to an array of samplenames
2) Samplename to the filename  
3) Samplename to condition
