CLASS ndi.setup.daq.reader.mfdaq.stimulus.vhlabvisspike2

  NDI_DAQREADER_MFDAQ_STIMULUS_VHLABVISSPIKE2 - Device object for vhlab visual stimulus computer

  This device reads the 'stimtimes.txt', 'verticalblanking.txt', 'stims.mat', and 'spike2data.smr' files
  that are present in directories where a VHLAB stimulus computer (running NewStim/RunExperiment)
  has produced triggers that have been acquired on a CED Spike2 system running the VHLAB Spike2 script.

  This device produces the following event channels in each epoch. They are not read from the CED SMR
  file but instead are read from the .txt files that are generated by the vhlab scripts.

  Channel name:   | Signal description:
  ----------------|------------------------------------------
  mk1             | stimulus on/off
  mk2             | stimid 
  e1              | frame trigger
  e2              | vertical refresh trigger
  e3              | pretime trigger

cedspike2filelist2smrfile - Identify the .SMR file out of a file list

FILENAME = CEDSPIKE2FILELIST2SMRFILE(FILELIST)

  Given a cell array of strings FILELIST with full-path file names,
  this function identifies the first file with an extension '.smr' (case insensitive)
  and returns the result in FILENAME (full-path file name).

cedspike2headertype2mfdaqchanneltype - Convert between Intan headers and the ndi.daq.system.mfdaq channel types

CHANNELTYPE = CEDSPIKE2HEADERTYPE2MFDAQCHANNELTYPE(CEDSPIKE2CHANNELTYPE)

  Given an Intan header file type, returns the standard ndi.daq.system.mfdaq channel type

epochclock - return the ndi.time.clocktype objects for an epoch

EC = EPOCHCLOCK(NDI_DAQREADER_MFDAQ_STIMULUS_VHLABVISSPIKE2_OBJ, EPOCHFILES)

  Return the clock types available for this epoch as a cell array
  of ndi.time.clocktype objects (or sub-class members).

  This returns a single clock type 'dev_local'time';

  See also: ndi.time.clocktype

eq - tests whether 2 ndi.daq.reader objects are equal

B = EQ(NDI_DAQREADER_OBJ1, NDI_DAQREADER_OBJ2)

  Examines whether or not the ndi.daq.reader objects are equal.

getchannelsepoch - List the channels that are available on this device

CHANNELS = GETCHANNELSEPOCH(THEDEV, EPOCHFILES)

  This device produces the following channels in each epoch:
  Channel name:   | Signal description:
  ----------------|------------------------------------------
  mk1             | stimulus on/off
  mk2             | stimid

id - return the identifier of an ndi.ido object

IDENTIFIER = ID(NDI_ID_OBJ)

  Returns the unique identifier of an ndi.ido object.

ndi_unique_id - Generate a unique ID number for NDI projects

ID = NDI_UNIQUE_ID

  Generates a unique ID character array based on the current time and a random
  number. It is a hexidecimal representation of the serial date number in
  UTC Leap Seconds time. The serial date number is the number of days since January 0, 0000 at 0:00:00.
  The integer portion of the date is the whole number of days and the fractional part of the date number
  is the fraction of days.

  ID = [NUM2HEX(SERIAL_DATE_NUMBER) '_' NUM2HEX(RAND)]

  See also: NUM2HEX, NOW, RAND

newdocument - create a new ndi.document for an ndi.daq.reader object

DOC = NEWDOCUMENT(NDI_DAQREADER_OBJ)

  Creates an ndi.document object DOC that represents the
     ndi.daq.reader object.

readchannels_epochsamples - read the data based on specified channels

DATA = READ_CHANNELS(MYDEV, CHANNELTYPE, CHANNEL, EPOCHFILES, S0, S1)

   CHANNELTYPE is the type of channel to read

   CHANNEL is a vector of the channel numbers to read, beginning from 1

   EPOCHFILES is the cell array of full path filenames for this epoch

   DATA is the channel data (each column contains data from an indvidual channel)

readevents_epochsamples - read events or markers of specified channels for a specified epoch

[TIMESTAMPS, DATA] = READEVENTS_EPOCHSAMPLES(SELF, CHANNELTYPE, CHANNEL, EPOCHFILES, T0, T1)

   SELF is the NDI_DAQSYSTEM_MFDAQ_STIMULUS_VHVISSPIKE2 object.

   CHANNELTYPE is a cell array of strings describing the the type(s) of channel(s) to read
   ('event','marker', etc)

   CHANNEL is a vector with the identity of the channel(s) to be read.

   EPOCH is the cell array of file names associated with an epoch

   DATA is a two-column vector; the first column has the time of the event. The second
   column indicates the marker code. In the case of 'events', this is just 1. If more than one channel
   is requested, DATA is returned as a cell array, one entry per channel.

readevents_epochsamples_native - read events or markers of specified channels for a specified epoch

[TIMESTAMPS, DATA] = READEVENTS_EPOCHSAMPLES_NATIVE(MYDEV, CHANNELTYPE, CHANNEL, EPOCHFILES, T0, T1)

   CHANNELTYPE is the type of channel to read
   ('event','marker', etc). It must be a string (not a cell array of strings).

   CHANNEL is a vector with the identity of the channel(s) to be read.

   EPOCH is the epoch number or epochID

   DATA is a two-column vector; the first column has the time of the event. The second
   column indicates the marker code. In the case of 'events', this is just 1. If more than one channel
   is requested, DATA is returned as a cell array, one entry per channel.

   TIMEREF is an ndi.time.timereference with the NDI_CLOCK of the device, referring to epoch N at time 0 as the reference.

samplerate - **

SAMPLERATE - GET THE SAMPLE RATE FOR SPECIFIC CHANNEL

  SR = SAMPLERATE(DEV, EPOCHFILES, CHANNELTYPE, CHANNEL)

  SR is an array of sample rates from the specified channels

 so, these are all events, and it doesn't much matter, so
  let's make a guess that should apply well in all cases

searchquery - create a search for this ndi.daq.reader object

SQ = SEARCHQUERY(NDI_DAQREADER_OBJ)

  Creates a search query for the ndi.daq.reader object.

T0T1 = T0_T1(NDI_DAQSYSTEM_MFDAQ_CEDSPIKE2_OBJ, EPOCHFILES)

  Return the beginning (t0) and end (t1) times of the EPOCHFILES that define this
  epoch in the same units as the ndi.time.clocktype objects returned by EPOCHCLOCK.
