Sff_Extract Question

Question

[Walter]

how do get the sff_extract download to work in mira ie copy file from bin to user directory

Answer 1

[User 59]

sff_extract (presumably from here) is a Python script. Assuming a) you have Python installed and b) the first line of the file points to #!/usr/bin/env python (or the location of your Python interpreter) then a simple

chmod 755 sff_extract; ./sff_extract

(or copy to a bin directory in your $PATH) should be sufficient. If you want to call it explicitly then

python sff_extract

will also work.

That is rather difficult to read. I think that you have copied sff_extract from scripts/ to /usr/local/bin. The errors are because you are not giving the full path to sff_extract. You need to do either chmod 755 scripts/sff_extract or sudo chmod 755 /usr/local/bin/sff_extract. Then, run it either as ./scripts/sff_extract (for the copy in scripts/) or just sff_extract (for the copy in /usr/local/bin - that copy should be in your PATH, type which sff_extract to see if it is). File paths are important in Linux - read up on them.
