Hi,

I downloaded NCBI's BLAST. Every time I try to run blastn it get permission denied. I moved it into the path I had put the path right before it. I changed the permissions with chmod -x blastn (which turned the executable from green to white). Is there an extra step in the install? What am I missing?

Thanks!

chmod -x removes execute right, +x adds it! Solved.

chmod -x blastn disables the execution of the file (clears the flag). chmod +x blastn is the required command.
