## Installation

### Dependencies:

- Windows OS (see **Camstim package**)

- python 2.7

- psychopy 1.82.01

- camstim 0.2.4

### Installation with [Anaconda](https://docs.anaconda.com/anaconda/install/) or [Miniconda](https://docs.conda.io/en/latest/miniconda.html):

1. Navigate to repository and install conda environment.  

    `conda env create -f environment.yml`

2. Activate the environment.  

    `conda activate allen_stimulus`

3. Install the AIBS `camstim` package in the environment.  

    `pip install camstim/.`

4. Download required video clips from [movie_clips.zip](https://tigress-web.princeton.edu/~dmturner/allen_stimulus/movie_clips.zip)

   Extract into the `data` directory.

   

### Input Files

The software requires two sets of input files. There should be a set of text files present under `data/stimulus_orderings` that indicate the display order of video clips for different phases of the experiment. In addition, there should be a set of video clips (stored as raw .npy files). These clips must be downloaded and extracted into the data folder from [movie_clips.zip](https://tigress-web.princeton.edu/~dmturner/allen_stimulus/movie_clips.zip)

### Stimulus design

1. For the random stimulus order (days #0 and #5):

   * there are 4 difference choices of a 2 sec duration stimulus 

     * movie clip A 

     * movie clip B 

     * movie clip C 

     * a constant grey screen, X

   * these will be displayed in a randomized order.

   * this order will be exactly the same on day #0 and day #5. 

   * there will be 525 repeats of each of the 4 stimuli.

2. For the sequence stimulus order (day #1 – #4):

   * the 3 movie clips are shown in the same repeated order, ABC, for 50 minutes. 

   * this will result in 500 repeats of this movie clip sequence. 

   * in the last 20 minutes, the stimuli will be shown in a random order with the grey screen intermixed, as on days #0 and #5

   * a different random sequence will be chosen and kept the same across days #1 – #4.

   * this will result in 150 repeats of each of these 4 stimuli.
