Intron splicing order of hnRNP A1. a The intron splicing order read count adjacent matrix of hnRNP A1. The intron index number is labelled in the first row and first column. b Reordering of the read count frequency matrix by most likely order; values \(\le\) 0.5 and > 0.5 are coloured differently. The values in the upper diagonal are larger than the values in the lower diagonal, which supports the most likely order calculated. For example, values in row 1 (corresponding to intron 4) \(\approx\) 0.9 and values in column 1 \(\approx\) 0 suggest that intron 4 was spliced before other introns
