Error with importing Bio package

[shaman-narayanasamy]

Dear authors,

I am interested in using ccontigs. Everything seems to be working well. However, I am receiving an error regarding the absence of the "Bio" package:

Is this something to be concerned about? I am attempting to run it in a cluster environment with an existing module of Julia ver. 1.1.1.

Please let me know if this is something to be concerned about, because when I attempt to launch the command, it does not work at all:

$ julia ccontigs.jl -i test/validation.fa -o test.tsv

Looking forward to hearing from you.

Very strange. I’ve had issues downloading Julia packages on clusters in the past though. Two questions. Can you load in that package when you run a Julia interactive session? Also does it run okay on your laptop or desktop?

[shaman-narayanasamy]

I was running in an interactive session in my attempt. I did not try it on my local machine.

For now, I just followed the instructions of the error and added the following lines to beginning of the ccontigs.jl script:

import Pkg; Pkg.add("ArgParse")
import Pkg; Pkg.add("Bio")

NOTE: The same error for "ArgParse" appeared after I imported the "Bio" package.

It worked both in interactive and batch mode. This is my first time using a Julia based tool, and therefore I am unsure if this is the best solution and may affect runs on other environments. Please let me know if I should try something else.
