Creates a data frame with unique, productive amino acid sequences as rows and sample names as headers. Each value in the data frame represents the frequency that the sequence appeared in the sample.
A list data frames of of productive amino acid sequences generated by LymphoSeq function productiveSeq where the aggregate parameter was set to "aminoAcid".
A character vector of amino acid sequences of interest. It is useful to specify the output from the LymphoSeq functions uniqueSeqs or topSeqs and subsetting the "aminoAcid" column. See examples below.
Returns a data frame of unique, productive amino acid sequences as rows and the % frequency it appears in each sample as columns.
