ImportNS

  ImportNS uses the NeuroShare library to import a data file under Windows

  ImportNS is called to load various proprietary file formats where the
  manufacturers have provided a NeuroShare compliant DLL. Communication
  with the file occurs via Neuroshare mexprog.dll

  ImportNS should not be called direcly but via one of the format specific
  import routines .ImportNS assumes that the appropriate NeuroShare dll
  has already been selected by a previous call to ns_SetLibrary and that
  the NeuroShare mexprog.dll (or mexprog.mexw32) is available.

  Example:
  MATFILENAME=ImportNS(FILENAME, TARGETPATH)

  FILENAME is the path and name of the Spike2 file to import.

  The sigTOOL (*.kcl) file generated will be placed in TARGETPATH if
  supplied. If not, the file will be created in the directory taken
  from FILENAME.


  Toolboxes required: None

  Acknowledgements: This routine calls the NeuroShare mexprog.dll and
  associated m-files to communicate with the various manufacturer specific
  NeuroShare DLLs
