Question

[Suraj Shah]

Hello,

I downloaded the NCBI nr database and also the md5sum files from the NCBI FTP site.. Now i want to check wheather the files are downloaded correctly. Please help me with the procedure to check the files.

Thanks.

This depends a bit on whether you are on Mac or Linux, on linux you have (GNU) md5sum which is a bit more powerful than the md5 program (found in BSD/MacOS). Try man md5sum. Doing md5sum -c md5sums.txt with all the files in the same directory and md5sums.txt containing the filenames and corresponding md5sums as downloaded from NCBI should do the trick in linux.
