angelucci_visstim - Create a new multifunction DAQ object

D = NDI_DAQREADER_MFDAQ_STIMULUS_ANGELUCCI_VISSTIM2(NAME, THEFILENAVIGATOR, DAQREADER)

Creates a new ndi.daq.system.mfdaq object with NAME, and FILENAVIGATOR. This is an abstract class that is overridden by specific devices.


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

EC = EPOCHCLOCK(NDI_DAQREADER_MFDAQ_OBJ, EPOCH_NUMBER)

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

For the generic ndi.daq.reader.mfdaq, this returns a single clock type 'dev_local'time';

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.

filenamefromepochfiles - return the file name that corresponds to the NEV/NSV files

[NEVFILES, NSVFILES] = FILENAMEFROMEPOCHFILES(FILENAME_ARRAY)

Examines the list of filenames in FILENAME_ARRAY (cell array of full path file strings) and determines which ones have the extension '.nev' (neuro event file) and which have the extension '.ns#', where # is a number, or the source data files.

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.

Help for ndi.daq.reader.mfdaq.stimulus.angelucci_visstim/id is inherited from superclass NDI.IDO


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.

read_blackrock_headers - read information from Blackrock Micro header files

[NS_H, NEV_H, HEADERS] = READ_BLACKROCK_HEADERS(NDI_DAQREADER_MFDAQ_BLACKROCK_OBJ, EPOCHFILES, [CHANNELTYPE, CHANNELS])

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 (cell array of strings, one per channel)

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

EPOCH is set of epoch files

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

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

SELF is the NDI_DAQSYSTEM_MFDAQ_STIMULUS_ANGELUCCI_VISSTIM 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

[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 - GET THE SAMPLE RATE FOR SPECIFIC EPOCH AND CHANNEL

SR = SAMPLERATE(DEV, EPOCHFILES, CHANNELTYPE, CHANNEL) CHANNELTYPE can be either a string or a cell array of strings the same length as the vector CHANNEL. If CHANNELTYPE is a single string, then it is assumed that that CHANNELTYPE applies to every entry of CHANNEL.

SR is the list of sample rate from specified channels

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.

t0_t1 - return the t0_t1 (beginning and end) epoch times for an epoch

T0T1 = T0_T1(NDI_EPOCHSET_OBJ, EPOCHFILES)

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

The abstract class always returns {[NaN NaN]}.

B = VERIFYEPOCHPROBEMAP(NDI_DAQREADER_MFDAQ_BLACKROCK_OBJ, EPOCHPROBEMAP, EPOCHFILES)

Examines the NDI_EPOCHPROBEMAP_DAQREADER EPOCHPROBEMAP and determines if it is valid for the given device with epoch files EPOCHFILES.
