TTL file

Depending on the acquisition settings, the analysis requiers different preprocessing steps to create the TTL file.

In any case, the script Localizer_getTriggers.m needs to be run, if possible step by step.

This script is calling the script Localizer_getPatInfos that needs to be updated with the patient that will be run.

% if Nlx TTLs evts, read event and define idx start and end of each loca in Localizer_getPatInfos

% [TTL_Timestamps, EventIDs, TTL_ID, Extras, EventStrings, Header] = Nlx2MatEV(fullfile(NlxPath, 'Events.nev'), [1 1 1 1 1], 1, 1, [] );

% NlxEvt = [TTL_Timestamps' TTL_ID']; %µsec

% NlxEvt = NlxEvt(TTL_ID>0, :); %µsec

% NlxEvt = [NlxEvt  (NlxEvt(:,1)-NlxEvt(1,1))*1e-6];

The outputs of the script are sanity checks figure and a .csv table that has to be used to create the .pos file.

With the .csv file you can compare the log file and the TTLs recorded. It is usefull to delete fake TTLs

Nlx2MM

This configuration is to be avoided .TTL if the triggers are not sent to Nlx and MM through a bipolar channel

TTLs are sent to Neuralynx that send them to Micromed:

...

Solution: take timing from neurlaynx Neuralynx and find the time dely delay between Neuralynx and Micromed to transpose the correct TTL timings to Micromed.

Find delay between Neuralynx and Micromed with the bipolar channels.

Neuralynx and Micromed in parallel

Trigger only via TTL

Find delay between Neuralynx and Micromed with a iEEG channel.

Trigger via TTL and bipolar voltage input

Find delay between Neuralynx and Micromed with the bipolar channels. For Micromed, there should be a bipolar trigger channel for each box in order to check the delay between the 2 boxes.

Micromed direct

Convert .TRC to ELAN

Launch.exe : F:\IR-IHU-ICM\Bureautique\EpiDBS\Epimicro\ExperimentProtocol\Localizer\DataLyon\Localizer - 21-02-2018\Localizer.exe

...

Select File and click on 'Convert to ELAN File

Remove the .TRC file from the loca folder

Create .pos,

This is the ELAN TTL file, that has to be created from the .csv file

3 columns separated with tabs, and save it as

pat_ccccc_mmmm_locaname_raw.pos

column 1 : sample

column 2 : TTL value

column 3 : 0

Electrodes names .eeg.ent

If some electrode have a number in the name, change the name frome the .eeg.ent to remove the number. Example: change Am2g1 to Amg1

Issues

• If electrode has a number in the name, name cut at the first number: ex Ha2g1 will be Ha2
• 2 "l" in Envelloppe"
• 2 "l" ans 1 "p" in Envellope"
