Heys @ilisulh ,
I imagine you don't have the function into the path. Try to run the command like this ./vdb-config when you are inside the folder containing that function.
If this works, you should see an interactive blue terminal. If you are running in mac catalina, when you try to save the new options, you will get the message "error saving changes". I'm in that step, let's see if we can fix it!

@ilisulh, which command did you run when you received This sra toolkit installation has not been configured.?

All sra-tools binaries are located in the same directory.
To get a valid sra-toolkit - download and unpack a tarball from https://trace.ncbi.nlm.nih.gov/Traces/sra/sra.cgi?view=software.

@ilisulh, do you still need help?
vdb-confiq is not a valid name.

you need to run the command,"./vdb-config --interactive" but not "vdb-config --interactive"

make sure that path contains your particular function. then write ./vdb-config --interactive. this will popup a dialogue box where you can enable the access.
