TLOAD is a functions for loading and triggering data.
Recently, automated rejection of trials with artifacts is added.
  [signal,HDR] = tload(FILENAME, TI, [CHAN,];

TLOAD uses SLOAD to load the data of file FILENAME. This file must contain trigger information (code 0x0300 according to eventcodes.txt) which is transformed into the HDR.TRIG information.

TI = [0,8] indicates the time interval (in seconds) relative to the trigger information. Optionally, CHAN can be used to to a channel selection.

For this purpose, an additional eventfile with artifact scoring has to be provided. This artifact scoring must be provided as GDF-file; it can can be obtained, for example, with SVIEWER from BIOSIG.

[signal,HDR] = tload(FILENAME, TI, [CHAN,] EVENTFILE [, AI])

The final parameter AI is optional again, an determines in which time window artifacts are checked. If AI is not provide, the same time window as TI is used.
