ImpedanceProject

The data analysis, project design code for the 2D impedance project. For more project information, refer to the google doc procedure and relevant proposals.

Folder structure overview:

DataAnalysis:

the preliminary analysis code that aligned the data and save the needed information in the output file. Simple plotting functions Flow order: FindMaxOnsetIndex - CheckDirectionReading - ForceData or PositionData - Plot ForceData

• Main: the main file to run that will initialize global variables to store the results, indicate if plots should be drawn, construct the condition index array as the current experiment setting, clean up and save processed data, plot the force data per condition.
• FindMaxOnsetIndex: finding the max relative movement onset index per trial (how many sample does it take from beginning of the trial to the first movement onset). Only need to be run once per experiment.
• CheckDirectionReading: need to run once per condition. Pull out the indexes to use in the big data array, arrange them in an array where each row corresponds to the indexes of one trial. The trials are in order: all trials in first repetition listed before next repetition, etc.
• ForceData: using the index to find the corresponding force at the sampling time, aline the data at movement onset time, arrange the data in alingedPosByBlock in order: allTrials for forceX, then forceY, then Fz, TorqueX,Y,Z; Save the processed data to the corresponding index in the final output variables.
• PlotForceData: plot the force for all directions per condition, 24 plots total
• PlotForceDataByGroup: not completed yet.
• PositionData: clean up and aline the position data, in a seminar fashion as the ForceData

Results:

sample results, mostly plots in jpg format

PartsDesign:

solid work and 3d printer Code for the parts printed

src:

main folder for experiment modules

Proficio_External:

robotic arm control code

data_loader:

code that translates the RTMS message to the saved data format. Invoked by the ProcessRawData common when running in matlab-shell under rg2/scripts

config:

key configuration files used by the experiment, specifying task conditions, force threshold, each state time, pass/fail conditions, reward levels, etc.

CerebusButtonReward.m:

The main matlab function to send reward. Normally under Documents/Matlab on the rig.
