3 MCS Specific Matlab Functions
All functions listed in the following can be executed by mcs_ExampleScript.
mcs_ExampleScript might serve as example and shows how to work with the given functions.
mcs_ExampleScript generates all parameters needed to run and to perform the following
Matlab functions:
- mcs_Info.m
- mcs_GetEntities.m
- mcs_Graphic.m
mcs_ExampleScript uses three predefined Neuroshare functions (“ns_...”) and a modified
Neuroshare function that is described in the next section of the text.
mcs_SetLibrary('nsMCDlibrary.dll') will always be the first step. This function opens
a Neuroshare shared Library and loads the appropriate DLL.
ns_GetLibraryInfo obtains information about the library.
ns_OpenFile opens a neural data file, specified by filename or pathway and returns a file
called hFile, that contains an identification number. This is important when you want to call
the following functions.
ns_GetFileInfo is a function that contains some information about the data file like FileType,
EntityCount, TimeStampResolution, TimeSpan, AppName, Time_Year, Time_Month, Time_Day,
Time_Hour, Time_Min, Time_Sec, Time_MilliSec, FileComment.FileType is given as a sequence
of abbreviations.
It is a combination of several properties: Layout, continuous or not, recorded streams.
For example:
FileInfo = FileType: 'MEA cont Di,El,An'
The Channel Type is named according to the title given in MC_Rack (first two letters).
Channel Types of streams which are not mapped up to now can be neglected.
