LePA Proteins is a learning tool that shows us all the intermediate steps and partial results of a pair-wise alignment of aminoacid sequences.

DIRECTIONS OF USE:

First of all, we have to introduce the two aminoacid sequences in the textfields (only the 20 aminoacid characters). Then we choose one of the three methods available:

Next we have to put the desired values to the GAP field which will be used in the calculations. Pressing the 'Matching Matrix' button we can see the matching values for all the aminoacids pairs in a new window.

To start we press the ALIGN button and we can see how two matrix appear in the visualization area. On the left side we have the Scoring Matrix which shows the partial punctuations of the alignment. And on the right matrix we can see the possible alignments until that moment.

There are four buttons:
