Looks like you have a 32 bit kernel and a 64 bit binary. You will have to install the 32 bit version.

I guess you picked up rightly....here is the configurtaion...

Linux raghul-laptop 2.6.32-31-generic #61-Ubuntu SMP Fri Apr 8 18:24:35 UTC 2011 i686 GNU/Linux

i686 means 32 bit right???

how could I upgrade the kernel?? is it a complicated process?

I checked and it says i have to install the kernel again...and If I do it what about my windows partition. Do I need to take a beckup...or repeat the whole process again???

I am sorry for all this question which I just blasted on you...i am new to linux...!!!

You can’t just upgrade the kernel, as you would have to upgrade all tools of the OS too, which means in the essence to reinstall Linux. What about installing the 32 bit version of the blastn application?

The only hitch is ...I dont know how to uninstall previous version from the system...i tried with syneptic manager/software centre..but all in vein..so if you can tell how to uninstall the previous install version from terminal..I will proceed with installing the 32 bit BLAST version...

If you only untar the archive you can get rid of it by just removing it again:
Code:
$ rm -rf /home/raghul/ncbi-blast-2.2.25+
Note that will remove the complete ncbi-blast-2.2.25+ directory.
