Import data from a PLX file.

Installation
Download the Import PLEXON's PLX.opx, and then drag-and-drop onto Origin workspace.
An icon will appear in the Apps Gallery window.

OPERATION

1. Click the Import PLEXON's PLX icon to launch the dialog.
2. Choose the PLX file to be imported.
3. A dialog will open, showing a list of available variables with checkboxes.
   By default all variables will be imported. 
4. Click OK button to load selected variable(s) into Origin.

LabTalk

You can use LabTalk script to import data from a PLX file, by calling functions written in Origin C.

1. Load Origin C prior to opening any PLX file:
   run.LoadOC(%@AImport PLEXON's PLX\OPLX.cpp, 16);
2. Open a PLX file, an integer ID representing the file will be returned:
   int nID = PLXopen(_plx_file_full_path_);  // _plx_file_full_path_
3. Get the name(s) of available variables:
   string timestamps$ = PLX_Timestamps(nID); // timestamp names separated by '\n'
string continuous$ = PLX_Continuous(nID); // continuous names separated by '\n'
string waveforms$ = PLX_Waveforms(nID);   // waveform names separated by '\n'
4. Select variable(s) to import:
   StringArray saTimestamps = {SPK01, SPK02};  // names of timestamps to import
StringArray saContinuous = {WB01, WB02};    // names of continuous to import
StringArray saWaveforms = {SPK01, SPK02};   // names of waveforms to import
5. Import the selected variable(s) into an existing worksheet, say, [Book1]Sheet1:
   PLX_GetTimestamps(nID, [Book1]Sheet1, saTimestamps);  // import specific timestamps
PLX_GetContinuous(nID, [Book1]Sheet1, saContinuous);  // import specific continuous
PLX_GetWaveforms(nID, [Book1]Sheet1, saWaveforms);    // import specific waveforms
6. To import markers into the existing worksheet, say, [Book1]Sheet1:
   PLX_GetMarkers(nID, [Book1]Sheet1);     // import the marker variable if there's any)
7. The loading process should always end by closing the file:
   PLXclose(nID);
