# This 2017.2 HSTDP release is based on Anaconda/Miniconda, Python 3.5

Perform the following steps in your terminal to install the release:
--------------------------------------------------------------------

For existing Anaconda3 or Miniconda3 installations:

  $ conda create -n hstdp-2017.2 --file http://ssb.stsci.edu/conda/hstdp-2017.2/hstdp-2017.2-linux-py35.0.txt

As bugfixes are announced your existing pipeline software may be updated by issuing the command:

  $ conda update -n hstdp-2017.2 --file http://ssb.stsci.edu/conda/hstdp-2017.2/hstdp-2017.2-linux-py35.%ITERATION.txt

Where %ITERATION is the next incremental version of the environment specification file served from that URL.
For example, this release's next bugfix update procedure would be:

  $ conda update -n hstdp-2017.2 --file http://ssb.stsci.edu/conda/hstdp-2017.2/hstdp-2017.2-linux-py35.1.txt


Updates will not be supplied via external installation add-ons as either tarballs or scripts.
Also, keep in mind that Conda, the package manager, may prompt you automatically to upgrade packages deemed out of date.
Some back-end preparation changes have been implemented with this build to align procedures with those used in the JWST build methodology.

A fresh installation of Anaconda3 or Miniconda3 is not required for each HSTDP release. The method described here allows for multiple, entirely segregated pipeline installations.

If you do need to install conda from scratch:

1. Install Anaconda3 or Miniconda3

For detailed instructions of this step, please visit: http://docs.continuum.io/anaconda/install#linux-install

For Anaconda:

  $ wget https://repo.continuum.io/archive/Anaconda3-4.3.1-Linux-x86_64.sh
  $ bash Anaconda3-4.3.1-Linux-x86_64.sh
  $ export PATH=$HOME/anaconda3/bin:$PATH

 For Miniconda (if preferred):

  $ wget https://repo.continuum.io/miniconda/Miniconda3-4.3.11-Linux-x86_64.sh
  $ bash Miniconda3-4.3.11-Linux-x86_64.sh
  $ export PATH=$HOME/miniconda3/bin:$PATH

2. Install the pipeline

  $ conda create -n hstdp-2017.2 --file http://ssb.stsci.edu/conda/hstdp-2017.2/hstdp-2017.2-linux-py35.0.txt

3. Enter a BASH shell

  $ bash

4. Activate the pipeline environment

$ source activate hstdp-2017.2
