s´lut les forumistes.
Le probleme m´a encore ete reposé sous la forme suivante:
On a un fichier, qui contient les Motifs de proteins suivants:
>PS00058
G-F-R-G-E-[AG]-L
>PS00059
G-H-E-x-{EL}-G-{AP}-x(4)-[GA]-x(2)-[IVSAC]
Le devoir est reecrire le contenu du fichier sous la forme suivante:
>PS00058
GFRGEAGL
>PS00059
GHEXELGXGAXIVSAC
Donc on doit annuler :[,],{,},(,),-
tout element annuler doit etre ecrit dans un fichier sous la forme (1, 2) pour[AG] par exemple ou (2,2) pour {AP}. En fait : 1 represente [; 2 represente {; 3---->(, 4-----> - et 0 si aucun des symboles n´est present.
Les chiffres prensents dans le string doivent tout simplement etre annulé.
J´ai pu developper ceci, mais ca ne marche.
Pouvez vous m´aider?
