Instance Method Details

#create_tags_clashes_message(duplicated_tags_combinations_with_indexes, first_row = 0) ⇒ Object

This method takes a hash of not unique tags combinations with indexes, i.e 'TT'] => [0, 3], ['CC', 'GG'] => [1, 5] and returns a message, in this example: 'Same tags 'AA', 'TT' are used on rows 1, 4.
Same tags 'CC', 'GG' are used on rows 2, 6.'' It is also possible to pass in the first row number (if tags combinations do not start on row 1)
