To install GBM data tools:

Prerequisites:

XSPEC provided by FTOOLS which is part of the HEASOFT software suite: https://heasarc.gsfc.nasa.gov/lheasoft/
The download link allows you to specify the files to include within the tar file. Xspec must be selected.  Although GSpec has been tested with XSPEC v12.8 and newer, we suggest installing v12.10 and newer to take advantage of newer XSPEC capabilities.

GBM data tools requires python 3.x to run, as well as the standard python Tkinter GUI package. For more information on how to install python go to https://python.org.
If you're not familiar with python or want to have most of the required libraries conveniently installed, we recommend Anaconda Python 3.x which can be found at https://www.anaconda.com/distribution/

Note:
It is recommended that a virtual python environment is created, but it not required.  Information on how to make a virtual environment can be found at:

Using 'regular' python 3: https://docs.python.org/3/tutorial/venv.html
Using Anaconda python 3: https://conda.io/docs/user-guide/tasks/manage-environments.html

Be sure to activate the virtual environment prior to installing GBM data tools. If you installed GBM data tools within a virtual environment, then you must activate it prior to using our software.


Install instructions:

(Note: if you are not using a virtual environment or anaconda python, then you may need to install the software as administrator using 'sudo' on Unix like environments or by using a Windows command window running as administrator. Also, make sure that the pip you are using is associated with python 3.)


For 'regular' and anaconda python 3:

$ pip3 install gbm_data_tools-0.9.1.tar.gz


Ensure that the python 3 scripts directory is in your path. The gspec application will be placed in the path, and you should be able to start it by using the following command within the terminal:

$ gspec

Uninstall instructions:

To uninstall type:

$ pip3 uninstall gbm_data_tools (notice the underscores)
