@AngryMaciek Please send me the links of the 2 dockerfiles after uploading them to dockerhub so that I can add them to the Snakefile.

Why hasn't the travis tests started for this PR?

I do not know, I expect that is due to changes in the Travis config file, since there are literally no other changes to the repo(?) You need to debug this: maybe remove your changes and add them line by line?

@krish8484 : I have finished my last task here: #12 + #40 . Since it was also related to the CI I suggest you update your local repo to avoid conflicts later. I have added separate builds on linux and osx, importantly for you: Singularity can be installed only on linux architectures. Therefore all your modifications should be enclosed in the if os=linux statement - please inspect the updated .travis to see examples.

We have the containers built:

• https://hub.docker.com/r/zavolab/pythonlogomaker
• https://hub.docker.com/r/zavolab/r-zavolab/tags (tag 4.0.0)

Feels good, after finally solving the singularity issue in travis.

@AngryMaciek You may review now, let me know if anything needs changing.
