Very bad course, this class did not provide any example file in the lecture the instructor used to demonstrate. NO one from the instructor teams answer discussion forums etc. The script for the video is also awful without any grammar and spelling check. A lot of tools can not be used now. So I need to find a new way myself to solve exam questions. This is really the worst course I have every taken in coursera and it is included in such a good specialization course series. Really hope JHU can re-consider replacing this course with another better class

This is a wastes of time. I drop the specialization because there virtual box give error to install for compatibility issues with new computers and there is barely any to no response, help or solutions from the instructors. Cousera should check this kind of things and make sure courses are updated or remove them

I'm very disapoited with this Command Line Tools for Genomic Data Science course as it has not been update. Therefore is very hard and sometimes impossible to follow it. I can cite as example Tophat which is a tool that has no support anymore and you cannot finish the course unless you have it installed.

A very difficult course in all aspects. The first week was acceptable, but as it moves forward the level of distress and the lack of understanding raises considerably. In one word = disappointed.

I have issues with VirtualBox. I was not able to install CENTOS on my computer using VMBox 7.0. The course need to integrate normal Unix environments from macs and PC.

This is the worst course that I've been taken.

Very bad or non-existent support

need to be more vivid!
