Problem with advanced option in Create Eventlist #117

Closed satyagopal closed 4 years ago

satyagopal commented 4 years ago

Description

The Netstation EGI files have text based event labels which I am finding hard to convert to understandable numeric event codes (initially programmed in E Prime 2.0) since the TRSP has two eval values stored in it (i.e. 0 and 1) but it is not present in the eventlist created through the advanced option. And also the eventlist looks clustered and unreadable to even think of what to write for a binlister for this file. This is an oddball data file.

Probably because I am a beginner I am finding it hard to translate the steps used for the sample data to my own experiment files due to the event code complexity. I have attached the eventlist text file. I have also attached what I enter in the advanced option. Any advice would be really appreciated.

[Description of the bug or feature]


Steps to Reproduce

  1. ERPLAB>Create eventlist
  2. Advanced option
  3. Write in event codes you want against the labels that are present.


Expected behavior:

Neat rows of values in the eventlist as in the example tutorial


Actual behavior:

Structure is the same but values are not in an understandable format


Versions
OS version [Windows 10]
Matlab version [R2016b]
EEGLAB version [14.1.2b]
ERPLAB version [7.0.0]
E Prime version [2.0]

Thanks for your time! Satya

The problem was with the choosing the appropriate event marker for the dataset, in EGI systems it is Code which gives the four letter code set with E Prime. And before importing the file, for EGI files only we have to use the Segmentation Markup tool to add numeric codes that ERPLAB can read.

This way we need not even use Advanced options. This made it work for me!
