Dear all,
I am having trouble writing data from my TMSi Porti 7 system to the FieldTrip buffer. I have tried both the tmsidriver.exe and tmsi2ft.exe tools, but I’ve focused my efforts on the latter.
I have the TMSi system connected to my PC via USB and have tested the connection by recording some data in Polybench without issue. When I attempt to run tmsi2ft nothing happens until I terminate the process, at which point the error message “Cannot initiate device” is displayed. The exact syntax I run in the cmd is
tmsi2ft config.txt -
where config.txt file contains the following (misc commented lines excluded)
[select]
25=Blip25
samplerate=2048
For testing purposes I’ve only got a bipolar electrode connected to the TMSi system, which is the channel listed in the config file.
For tmsidriver.exe I changed the sampling rate in parameter file to match my system to attempt to get it to work, but no success there either. I also have the buffer open when running tmsidriver.exe. The contents of preferences.txt is
sampleRate(milliHz) BufSizeFactor savedata(0/1)
2048000 5 1
The TMSi Porti 7 system has a sampling rate of 2048Hz. The PC is running Windows 8.1 64-bit. I’m using fieldtrip-20171106.
Any advice or suggestions is greatly appreciated.
Best regards,
Jostein Holmgren
