Can't read .SMR data into FT

[Vladimir Litvak]

Dear Eduardo,

The version of Neuroshare included in Fieldtrip should be sufficient
although I'm not sure whether it's added automatically to the path.
One additional thing you might need is the DLL from CED that can be
found at:

http://www.ced.co.uk/upnssonu.shtml

You can put it in the neuroshare directory. Note that this setup
doesn't support SMR files from recent versions of Spike 2 (6 and up).
For these versions you can export the data into mat files and these
files are supported by fileio.

Best,

Vladimir
