From SEGUL's user Rohit Rannavre:
Currently, SEGUL does not support the computation of uncorrected p-distances for sequence alignments. This feature is available in software like MEGA, but MEGA can be slow for large datasets. I would like to request that SEGUL implement this functionality with options similar to MEGA, such as pairwise deletion of gaps, complete deletion, handling of missing data, etc.
Adding this feature would make SEGUL a more versatile and time-efficient tool for sequence analysis.
