Computer control of TMS machines

Click here for the document describing Nafi's TMS system

Both machines (MagStim and Nafi's) use a National Instrument USB Data acquisition card (referred to here as NIDAQ). However the Presentation Library for these two machines are different. Here is the one for Magstim: [1] and here is the one for Nafi's: [2]

The NIDAQ needs to be defined in Presentation (under Settings --> Port) as 3 output ports. For each port, "USB-6501" should be selected. For the first port choose "Data source: port0", for the second one choose "Data source: port1", and for the third one choose "Data source: port2". For Nafi's nothing else needs to be changed. For MagStim the "Inversion mask" of the seond port needs to be changed to 255 (because they have used inverse logic for their trigger circuit).

Using Brainsight navigation

Create a new project and load the anatomical images (NifTi file). Optional: load functional images as well if available/needed. Note that some preprocessing is needed to make the functional images have the same resolution as the anatomical. See: http://openwetware.org/index.php?title=Beauchamp:TMS&action=edit&section=5 Then generate 3D brain reconstruction and
