Eyal and Musaab- Recording session, no special events

Jan 10 2018

Meeting Notes:

Add CLUT to path
to get out in case of emergency, in case a door is locked, check the M&B door
People get wikis via a Wiki admin
Necessity for a lab manager?
Who orders towels?
Clean stuff please!
Placing electrodes into to cupboard or into the Faraday cage?
Charging batteries - store them fully charged? fully charge only when needed? --> [Lena] Biosemi gives two hints for storing batteries unused for a longer time (over a month): 1) store them half-charged; 2) store them in a dry, cold place (preferably a dry fridge).
Add more flashy clean notes to wiki
Remove the Acq1?
What about the CRT monitor photodiode? Ask Nico?

Dec 21 - 22 2017

Dc in EEG lab for updating the wiki with documentation.

Computers were OK, but Stimulus 1 did not immediately boot with SyncMaster at 100hz.
- Solution was to select the port on the 8 in 1 out VGA selector for stim 1, open the ATI Radeon catalyst viewer app, and click "detect monitors", then force the 100hz refresh rate.
- the problem can be completely avoided if you boot the stim computer with the port for the 8 in 1 out selected at the time of power.

DC in for color calibration with photometer.

Gamma table for color located on new stimulus computer at C:\Computer info\matlab\colorCal\ourcal.mat C:\Computer info\matlab\colorCal\monitorColorCalDemo.m shows how to load it and use it.

Eyal? please double check?

Dec 8 2017

Eyal reported a difference between how the old stimulus computer and the new stimulus computer display the color red on the CRT monitor. Dan Cook in for color calibration with photometer.

Dec 5 2017

Eyal- 16:30-19:00 - everyhing works properly

Dec 4 2017

Dan Cook in for Gamma calib.

Eyal take over for experimenter calib.

Dec 3 2017

CRT monitor and Dell monitor were not being recognized by the new stimulus computer. Problem fixed. Please see the pdf in C:\Computer info\monitors\CorrectSettings.pdf for the correct settings.

Media wiki not displaying thumbnails correctly.

Python

The Anaconda 4.3.30 distribution of Python 2.7.14 is installed.

You can find the Python and conda executables in the path:

C:\Anaconda\python
C:\Anaconda\Scripts\conda

The Ananconda prompt (terminal) is in the task bar, you can use that, or powershell.

Instead of using the root environment of Python 2.7 from the Anaconda prompt, please use either 1) your own environment, or 2) use the environment: python27

To use this version/environment of python, open the Anaconda prompt or powershell and type:

activate python27

You can install/update packages within this environment, but it is better if you create your own environment. Create zour own like this:

conda create --name my_python27

or, if you want to use a different version of python (one that is not the root version of 2.7),

conda create -n my_python36 python=3.6

where "my_python27" is your unique name. Afterwards, you can activate your own environment in the prompt whenever you want, and then manage your dependencies within your own environment without messing with anyone else's dependencies:

activate my_python27

You can read more about managing environments in conda here.

As of the time of writing, the following environments are located on the system:

dcook_python27 C:\Users\AG Villinger\AppData\Local\conda\conda\envs\dcook_python27
dcook_python36 C:\Users\AG Villinger\AppData\Local\conda\conda\envs\dcook_python36
python27 C:\Users\AG Villinger\AppData\Local\conda\conda\envs\python27
python36 C:\Users\AG Villinger\AppData\Local\conda\conda\envs\python36
root C:\ProgramData\Anaconda2

You can update the list by asking conda to list the environments:

conda info --envs

Nov 2 2017

show stuff in path:

($env:Path).Replace(';',"`n")

set path:

$env:path="$env:Path;C:\Anaconda\python"

installed older version of pyschopy:
conda install -c cogsci psychopy
psychopy: 1.82.01-py27_0 cogsci
pyglet: 1.2.4-py27_0 cogsci

Sending some triggers in Python:

from psychopy import core

port = parallel.ParallelPort(address=57336)

port.setData(0)

port.setData(1)

core.wait(1.0)
