Hi Vishaal, Welcome to yt! First, I think it might help to explain what yt's load function does. yt can operate on datasets produced by a number of simulation codes. The data format for each of these codes is pretty different, but usually yt can figure out what type of data it's dealing with by the format of the file that is given to the load command. Even then, the input must be of the form of one of the supported simulation codes. For a list of which codes are supported, you can check here: http://hg.yt-project.org/yt/wiki/CodeSupportLevels To help you further, we will need a little more information. Are you working with data from a certain simulation code? What does this file look like and how specifically would you like to visualize it? Finally, $YT_DEST is meant to be an environment variable that you could set. So for example, if your stuff was in /home/software/src/yt-hg/test you could have in your .bashrc file export YT_DEST=/home/software and then cd $YT_DEST/src/yt-hg/tests would take you right there.

Hi! I am an undergraduate student who is tasked with learning YT. I have gotten it to to work in command line and in the python shell with the given data set, but I am tasked with visualizing an ASCII data file of a single halo. Is it possible to import ASCII data sets with the load() function in the python shell?

Also, to get my python shell working I have to input $ cd /src/yt-hg/tests instead of the cd $YT_DEST/src/yt-hg/tests suggested in the orientation session. Do you know why this might be?

Thank you for your time.
