Hi,

Im stuck on a problem where I need to count the occurences of an Id in a hash. The Id is the value and the key is a string that contains a key word.

An example is:

            KEY                          Value
Affy:HG_U133A:213119_at:74:303; ENSG00000123643
Affy:HG_U133A:213119_at:542:439;        ENSG00000123643
Affy:HG_U133A:213119_at:658:369;        ENSG00000123643
Affy:HG_U133A:213119_at:199:255;        ENSG00000123643
Affy:HG_U133A:213119_at:436:453;        ENSG00000123643
Affy:HG_U133A:213119_at:324:381;        ENSG00000458158
Affy:HG_U133A:213119_at:584:557;        ENSG00000123643
Affy:HG_U133A:213119_at:234:507;        ENSG00000123643
Affy:HG_U133A:213119_at:482:429;        ENSG00000123643
Affy:HG_U133A:213119_at:608:451;        ENSG00000458158
Affy:HG_U133A:213119_at:356:297;        ENSG00000123643

What im after is to count the Ids for the the highlighted string Affy:HG_U133A:213119_at:356:297; , and then to choose the most reguarly occuring one. So this would give me:
213119_at : ENSG00000123643 = 9 (thank you wfsp)
213119_at : ENSG00000458158 = 2

I would then choose ENSG00000123643 to store in another hash with 213119_at, e.g. 213119_at{ENSG00000123643}.

I have looked at 100967 but its not what im after.
Does anybody have any ideas ?

cheers,
MonkPaul.
