<div>Hi Sophie,<br>
<br>
If you specify a file and path, you don't need ./ in front
of it, only when you try to execute a file in the current
folder. In our local fieldtrip distribution for biosemi2ft,
contrary to yours, apparently the extension .maci is missing
so you need to specify the extension as well:<br>
If you are in the folder:<br>
./biosemi2ft.maci (with optional parameters)<br>
<br>
or from anywhere else:<br>
../fieldtrip/realtime/acquisition/biosemi/biosemi2ft.maci
(with optional parameters)<br>

<div>Hi Sophie<br>
<br>
I've checked the script that we use to startup the buffer in
our lab. Apparently you need to type ./ before the command.
This is what our script looks like:<br>
cd to the /fieldtrip/realtime/acquisition/biosemi/ folder.<br>
Then run the biosemi2ft: ./biosemi2ft (with optional
parameters)<br>
<br>
I think you can also put a path in the gdf filename, so it
does not save it in the fieldtrip folder, but you will have
to check that.<br>
<br>
I hope this works for you!<br>
Best, Marianne<br>

Hi Marianne,<br>
<br>
There are 3 biosemi2ft in that folder : biosemi2ft.cc,
biosemi2ft.exe and biosemi2ft.maci; but when I type
../fieldtrip/realtime/acquisition/biosemi/biosemi2ft<br>
in the command line, it says No such file or directory.<br>

Hi Sophie<br>
<br>
Are you sure that the correct version of the biosemi2ft (so
the one for the mac) is in the folder that you are
specifying? Maybe you can try it first without the optional
parameters, so just<br>
../fieldtrip/realtime/acquisition/biosemi/biosemi2ft<br>
<br>

Hi,<br>
<br>
I tried it on Windows too, and it works perfectly.<br>
<br>
But I’m a Mac girl ☺ and I will be happy if someone could
help me.<br>
<br>
Thank you<br>

But, unfortunately I don't know about the Mac OS.<br>

Dear Sophie and Hamza,<br>
<br>
The connection between the Biosemi Active2 system and the
FieldTrip buffer is handled by interfacing software
biosemi2ft (part of fieldtrip), and should be started from
the terminal (mac) or command prompt (windows).<br>
<br>
The interfacing software is located in the FieldTrip folder:
../fieldtrip/realtime/acquisition/biosemi/biosemi2ft<br>
<br>
The BioSemi system needs a configuration (.cfg) file in
which some acquisition-related settings are specified.
Configuration files for the BioSemi system specify for
example from how many channels data should be streamed
and/or recorded, and whether the data should be downsampled.
For more information about configuration files for different
acquisition systems, see the Fieldtrip website<<a
moz-do-not-send="true"
href="http://fieldtrip.fcdonders.nl/development/realtime/biosemi">http://fieldtrip.fcdonders.nl/development/realtime/biosemi</a>>.<br>
<br>
To start the buffer that connects to the Biosemi Active2,
open the terminal (Mac) or command prompt (PC) and in the
folder where you would like to save your data execute
(change path according to your system and location of
fieldtrip toolbox):<br>
<br>
../fieldtrip/realtime/acquisition/biosemi/biosemi2ft
<config_file> <gdf-file> <hostname>
<port><br>
<br>
<br>
<br>
<config_file>: configuration file<br>
<br>
<gdf-file>: base name of the gdf file. The suffix .gdf
and session counters will be added automatically.<br>
<br>
<hostname>: optional, default is 'localhost', specify
'-' to spawn a local buffer (recommended)<br>
<br>
<port>: optional, default is 1972<br>
<br>
an example:<br>
<br>
../fieldtrip/realtime/acquisition/biosemi/biosemi2ft
myconfig.cfg myfile - 1972<br>
<br>
Note that the manually specified name of the file will
overwrite any existing file, so make sure myfile.gdf doesn't
exist.<br>
Once this is running, you get access to the data through the
fieldtrip buffer filled with data by biosemi2ft, i.e.,
fieldtrip fileio functions give you access to the data:<br>
ft_read_header('<a moz-do-not-send="true"
href="buffer://localhost:1972%27">buffer://localhost:1972'</a>),
or<br>
ft_read_data('<a moz-do-not-send="true"
href="buffer://localhost:1972%27,%27begsample%27,1,%27endsample%27,100">buffer://localhost:1972','begsample',1,'endsample',100</a>,........<br>
For further information, see fieldtrip website.<br>
<br>
(more info on how we use the system at our department can be
found here: <a moz-do-not-send="true"
href="http://www.nici.ru.nl/brainstream/twiki/bin/view/BrainStreamDocs/DocsSectionsInstallation">http://www.nici.ru.nl/brainstream/twiki/bin/view/BrainStreamDocs/DocsSectionsInstallation</a>)<br>
<br>
Hope this helps you to get things running in your place. If
you have any further questions, just let me know.<br>
