Off topic:export PATH= fails...!

Question

[T_18]

Dear all,

To run the program MCSC I need to add the diamond binary file into my executable search path. The path to the program is "/media/biosys5/bigDisk/Users/Programs/diamond"

So I tried: export PATH=$PATH:/media/biosys5/bigDisk/Users/Programs/diamond

also: export PATH=/media/biosys5/bigDisk/Users/Programs/diamond:$PATH

And even adding the first line into my .rcbash file. After all doing that calling "diamond" results in "No command 'diamond' found, did you mean:"

What am I doing wrong and how can I get this running with just calling diamond?

Thanks in advance!
