For 2023 - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
help in perl

Posted by sirisha (sirisha), 18 January 2008
I have a small doubt regarding my program. Hope you will help me in solving that.



let the input seq is "ttttttttttagaaaagavtttggyttttttt";

here the input matches with $a only with the letters in bold     :      ttttttttttagaaaagavtttggyttttttt

i want to know what we can do to give input showing both matches and mismatches in the input.(mismatch shold me shown as a hiphen)
That means the output should be like this:
The given sequence matches with the pattern at - - - - - - - - - - agaaaagav- - -ggy - - - - - - -

Hope you will help me in solving out this.

Thanks in advance,
