how to get the data of circular variance for orientation tuning ? #642

Closed windform2015 closed 8 years ago

windform2015 commented 8 years ago

Dear Bednar group members, I would like to analyze circular variance of orientation selectivity, so I need to record the data of responses of single units to different orientations, but I have no idea which commands can do it. I don't use GUI to plot the orientation tuning curves but run the script on the terminal. Could you give me some hints, please ?

Can you tell me which commands you are running in the terminal, i.e. what the script is doing?

windform2015 commented 8 years ago

Sure, the command is : python gcal.py. I am wondering what commands could be added in the srcipt to record the data as I mentioned above.

jbednar commented 8 years ago

Ah, I see. You can run "measure_or_tuning" (if you want to measure it for a single unit, using a circularly masked grating) or "measure_or_tuning_fullfield" (if you want to measure it for all units at once). These commands are defined in the FeatureMapper submodule (see http://ioam.github.io/featuremapper/_modules/featuremapper/command.html). If you import those commands from that file, then call them, the result should be something with data that you can unpack to see the responses to the various input patterns.

Thanks so much for your clues. Howver, I still have no idea which specific command to record the data in the final step. For example, for the data of orienation selectivity, we could call measure_or_pref first, then use "topo.sim.V1.views.maps.OrientationSelectivity.V1.last.data". How about this case, please ?

I think this was just answered in a different issue, #658.
