Hi all I have the following data that I'd like to further explore from decideTests > summary(DTresults) Germball Cerc TwoDay SevenDay TwentyOneDay AdultWorm Egg -1 1035 868 764 561 706 415 826 0 4891 5057 5144 5520 5178 5573 5150 1 602 603 620 447 644 540 552 I'd like to access particular parts of the tests results and was wondering if there was an easy way of doing this ? There are seven treatments (Germball, cerc etc) I'd like to create lists of genes from uniquegenelist that are: only downregulated in all treatments only upregulated in all treatments only up/down in one specific treatment or a couple of treatments Is this possible ? using grep or likewise ? If so could someone show me an example please ? I know that by looking at the results directly e.g. Germball Cerc TwoDay SevenDay TwentyOneDay AdultWorm Egg [1,] 0 0 0 0 0 0 0 [2,] -1 1 0 0 -1 0 0 [3,] 0 1 0 -1 0 0 1 [4,] 0 0 0 0 0 0 0 [5,] 0 0 0 0 0 0 0 6523 more rows ... You have the gene information or can apply a unique genelist to it Is this atall possible ? Many thanks for any help or advice Jason -------------------------------- Jason Skelton Pathogen Microarrays Wellcome Trust Sanger Institute Hinxton Cambridge CB10 1SA Tel +44(0)1223 834244 Ext 7123 Fax +44(0)1223 494919
