Re: filtering data

You can use the !SET qualifier to transform the generation factor into
another value and then filter on that.

For example, if you want generations 3, 6, and 9, I think you could go
something like:
Title line
  Gen 16 Data
  Gen369 2 !=V1 !SET 1 1 2 1 1 2 1 1 2 1 1 1 1 1 1 1
Datafile.data !FILTER Gen369 !SELECT 2

If you want only stuff after a set generation then you could specify the
generation from the command line and drop

Title line
  Gen 16 Data
  GenSel !=V1 !>$A !D 0
Datafile.data

  Subject: Fw: filtering data

  Hello -

  I have a quick question regarding filtering data. I'm running some animal
models and want to do this in some subsets as well as in the full data set.
  For example I have data on animals from 15 generations and using the data
file qualifier

  !FILTER generation !SELECT 4

  I can restrict the data set to just those animals in generation 4.
However, is there a way to specify a range of values to accept in the
"generation" field e.g. if I wanted to use animals in all generations
greater than 4, or in generations 4 - 8? Obviously I could build different
data files for these subsets but I am hoping there might be an easier way.

  Cheers,

  Alastair
