Question

[majeedaasim]

I am using Ubunto 16.4. I just installed the IGV with following commands sudo apt-get update sudo apt-install igv

When I try to run it by running the command

igv, following error is shown

I would suspect that you're running without a X11 environment. What happens when you run the following command:

echo ${DISPLAY}

what's your version of java ?

java -version

how do you start IGV ?

[majeedaasim]

I start IGV by simply typing igv in the terminal

aasim@aasim-ProLiant-ML150-Gen9:~$ echo ${DISPLAY}:0

aasim@aasim-ProLiant-ML150-Gen9:~$ java -version
