Hi Group,
Is there any function which would help in converting data from probe level
to gene level by averaging the expression of all the probes corresponding to
a gene.
For eg:
                         array1      array2
probe 1 Gene 1    2                 4
probe 2 Gene 1    4                 3
probe 3 Gene 2    5                 4

result:
            array1 array2
Gene1    3           3.5
Gene 2   5           4
Could any one give some ideas to perform this?
Thanks,
Viritha
