Exemple : AAAAAGGTTTTCTCTCTCTAAGGTTAAAAAAAAAAAAAAAAAAAAAAAAAA
I want to cut it in AAG and exactly after the first A so then i want to add the A like sufix to the first chain and AG like a prefix to the second one :
AAAAAcut here AGGTTTTCTCTCTCTAcut hereAGGTTAAAAAAAAAAAAAAAAAAAAAAAAAA
first chain: AAAAA +A
second chain:AG+GTTTTCTCTCTCTA
third:A+AGGTTAAAAAAAAAAAAAAAAAAAAAAAAAA
P.S no suffix to the last chain and no prefix for the firs one

Re: PLS an urgent SOS!
Does that mean you need this for an exam... If so you are not earning anything by us supplying an answer. We will assist you however if you need help.Mei_mei wrote: it's up to that script my whole exam
To start with here are a few things which may be of use...
To get a string from a certain point use stristr
To get the length of a string use strlen
To convert a string to an array you can use ( strlen
To use a loop and add to an array you need to use str-split
Finally to extract 1 character you can use substr
Using this information it is fairly easy to do what you want. If you produce some code and have problems, post your code and I am sure we will help more.
