NameError: name 'Signac' is not defined

[thatsfine]

Hi febret!

I just today downloaded the tar.gz file containing the latest release of firefly from your website which I have checked against the latest commit 70b3700 and it appears to match. Pretty cool how you got that tar.gz download button on your website to match up with the latest commit to master on GitHub!

But back to the issue at hand. I'm getting a very general Name error when attempting to run the command orun firefly.py after having preprocessed a hdf5 data file into a .xyzb file as shown in the tutorial on your website. You can see the bash output below. Am I doing something wrong or is there a problem with the way that Signac is called on line 4 of firefly.py? Just to confirm, I do have signac installed.

Any thoughts on why this could be happening? For background I'm running OSX 10.11.5 on a MBP Retina 13-inch, Early 2013 and have a Intel HD Graphics 4000 1536 MB card installed. According to Apple's developer website my system has OpenGL v4.1 installed as well as GLSL v4.10.

Hi Charlie,
thank you for your interest in firefly!
The current version of the code is a heavy work in progress. To be honest I'm surprised you were able to run anything at all since we are in-between commits :)

Instead of trying to solve your current error my suggestion is: stay tuned. We will be posting a lot of new stuff in the next couple of weeks that will hopefully address all your current problems.

By the way: one new feature that I'm working on now is direct loading of hdf5 files, so you will be able to skip the conversion step.

I see! You're right, I am surprised that I could run anything at all between commits. I'm here working with Phil Hopkins and Cameron Hummels at the TAPIR lab at Caltech and was told that you were in the process of updating the code so I'm excited to see where it leads! Could you drop some hints as to some more of the new features you're adding to the project?

Major things are

• ability to use arbitrary data fields to colors on the data
• customizable color maps
• ability to use another data field as a real time filter to choose a range of visible points
• custom rotation pivots
• simplified installer
• support for multipart hdf5 files
• (probably a little later) velocity vector display

Hi Alessandro!

I just pulled down the latest version of the code that you committed 3 days ago, and it seems that I'm still experiencing the same error that I originally submitted 21 days ago. It occurs on line 4 of firefly.py. My terminal output is shown below:

Is the code still a work in progress and have you experienced this error? I've reproduced the same error on two of my collaborators' computers all when running the same version of the firefly code (74bd6ac). Keep in mind we do have omegalib installed, as we are able to run the previous version of firefly without issue (bb0f626).

Hi Charlie,

we are pushing the first version of the new firefly today or tomorrow: what OS are you on?

[thatsfine]

I'm using OSX El Capitan. Version 10.11

FYI I just uploaded a working version (still work in progress but can be tested) for windows, I'm working on OSX compatibility. I'll give you another update tomorrow to let you know how far along we are with this.
