4 temp values is overkill. You only need 2 (one for the a<->z and one for the g<->c; you can actually use the same char for both).
atgcacgt a->z : ztgczcgt t->a : zagczcga z->t : tagctcga g->z : tazctcza c->g : tazgtgza t->c : tacgtgca atgcacgt tacgtgca So, you get the correct compliment. --Ben Dawson, Michael wrote: > Replace() will work if you use *four* temporary values. > > Replace 'a' with '1' > Replace 'c' with '2' > Replace 'g' with '3' > Replace 't' with '4' > > Then > > Replace '1' with 't' > Replace '2' with 'g' > Replace '3' with 'c' > Replace '4' with 'a' > > Then, you mix in some love and you have a dino-baby. > > M!ke > > -----Original Message----- > From: Jeff Congdon [mailto:[EMAIL PROTECTED] > Sent: Tuesday, June 14, 2005 2:41 PM > To: CF-Talk > Subject: Re: reverse compliment a sequence > > the replace idea won't work. it will replace all 'a' with 'z', then > replace all 'z' with 't' > > this leads to all 'a' being replaced with 't', not with all 'a' being > replaced with 't'. > > ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Logware (www.logware.us): a new and convenient web-based time tracking application.
