Hello,

I can't manage to remove particular columns of my multidimentional dataframe (matrix). It's not strictly duplicates.

Let's consider the matrix below :

my @matrix = (
    [t1 t1 t2 t2 t2], <- transcripts
    [a1 a2 a1 a1 a2], <- alleles
    [intron intron UTR_CG UTR UTR], <- locations
);

In fact, I would like to delete colums where I have "UTR" alone for a given transcript and allele, but ONLY when I already have a column with "UTR_CG" for the same given transcript and allele. For instance, the resulting table would be :

my @matrix = (
    [t1 t1 t2 t2],
    [a1 a2 a1 a2],
    [intron intron UTR_CG UTR],
);

Thank you so much in advance!
