We used the SimNIBS program to account for any potential overlap of the two sites of stimulation we wanted to apply and found the program to be very helpful! In using the program, I noticed that the default coil files currently offered are the Magstim 70mm F8 coil and the MagVenture MC B70. I also had a look at the other coil types offered, but could not find the specific one we used (the MagVenture Cool DB80). I was wondering if it would be possible to include this coil type and how this could be accomplished. Looking forward to hearing from you.

I noticed that the leadfield matrix created with TDCSLEADFIELD that is stored in the hdf5 file has dimensions: [3 x number of nodes x number of EEG electrodes]. I was wondering what the first dimension of 3 here represents. Is it the current density split into the X, Y, Z components? 2. I'm trying to import my own EEG cap for the leadfield calculations. In the EEG cap CSV file, I noticed that reference electrode is labelled as 'ReferenceElectrode' as compared to other electrodes which are just labelled 'Electrode'. Is there another label for the ground electrode or should I just omit it from the CSV file? 3. I noticed Oula mentioned that SimNIBS 4.0 is available from this abstract submission. According to the abstract, SimNIBS 4.0 supports lead-field calculations, which allows the improved head modeling to be integrated into EEG source reconstruction algorithms. I was wondering where we could download and install version 4.0, since the latest one I can find is version 3.2. I'm also interested to know if this new version of SimNIBS come with EEG source inversion algorithms (i.e. MNE, LORETA) as well. Currently, I'm looking into how I can read the leadfield computed by TDCSLEADFIELD() into fieldtrip to do source inversion, but if SimNIBS 4.0 comes with support for these algorithms as well that would be very nice!

However, do you only have a nifti file or can you use a dipole expansion .ccd file? From the dipole expansion you can easily calculate the B field at any desired point (this would be easier and you would simply need to calculate the field for all desired points in the mesh). If you do need it from the nifti file then I'd calculate the curl of dA/dt on the grid like you are doing and then interpolate to points in the mesh. I think I have some code to do this (likely python though) if that can be helpful for you.

Or TMS mechanism Message-ID: Dear friends, If you are familiar with it? please answer. Recently, I am studying the comparison between Transcranial Magnetic Stimulation (TMS) and tDCS. The essence of TMS is the magnetic modulation, is it right? Or is the essence of TMS the promotion of blood flow by a magnetic field? So, like the magnetic field in MRI, the magnetic field force rotatations of all electrons in the same direction? Or does TMS work by inducting electric fields and currents? But the frequency of TMS is only 1-25 Hz.  There's an explanation, saying TMS is delivered to the brain by passing a strong brief electrical current through an insulated wire coil placed on the skull. This rapid phasic current flow generates a transient magnetic field, which propagates in space and in turn induces a secondary current in the brain that is capable of depolarising neurons if the coil is held over the subject?s head (Pascual-Leone et al., 2002).

However, the frequency of a single TMS pulse is ~ 3 to 7 kHz, which is high enough to induce currents that are strong enough to depolarize the membranes.

Yes, the leadfield is calculated for the x, y, and z components. 2. Just omit the ground electrode. The electrodes in the forward solution should correspond to the electrodes in your data. Please be aware that due to the way the forward problem is solved with TDCSLEADFIELD (using reciprocity), you will need to multiply by -1 when using it for EEG source analysis. Also, the number of channels in the leadfield is one less than in the cap file because one of them is used as reference during the simulation. You will need to add this yourself afterwards (all zeros). In the hdf5 file, the attributes 'reference_electrode' and 'electrode_names' in mesh_leadfield/leadfields/tdcs_leadfield should tell you which electrode was used as reference and the names of all the electrodes, respectively. Also, if you use an average reference in your inverse analysis, remember to also convert the forward solution to an average reference. 3. We are currently working on SimNIBS 4.0 but it is not quite there yet. It will probably be a while before it is released but I do not know the exact plans. To my knowledge, we do not plan to implement inverse solvers in SimNIBS as there are plenty of great implementations available already, however, we do plan to allow people to interface with other packages. I believe we will support MNE-Python and perhaps FieldTrip. That way you should be able to integrate forward solutions from SimNIBS with inverse solvers from these software packages. Let me know if anything is unclear.

I'm guessing it might be related to an incompatibility between the display driver implementation of OpenGL and pyopengl/pyqt. One thing to try would be to update pyopengl in your simnibs environment and/or pyqt5 (we are using a somewhat outdated version, as we never tested with newer versions) and see if that helps.

This type of error is typically caused by missing features in the openGL driver, can you provide us with the actual version of the Nvidia driver - then I'll try to check if the functionality is supported in the version, I'm afraid that the latest version of the FX series driver for WIndows 7 was back in 2012 so it might be that it is not supported. You could also try to use driver supplied with Windows - or alternatively update to a newer version of Windows or replace the graphics card - unfortunately only quite old drivers exist for the FX 3500 on Windows. > > > > > > Best, > > > > > > Kristoffer > > > > > > > > > > > > On Wed, 17 Mar 2021 at 14:15, Nuno Luz wrote: > > > > > > Hi SIMNIBS Support, > > > > > > We have a problem starting SIMNIBS on a Computer with Windows 7 x64, 8gb RAM, Graphics Card NVIDIA QUADRO FX 3500. > > > > > > We already updated grapchics driver. > > > > > > The Error is: > > > > > > Here is the install_log.txt attached. > > > > > > > > > > > > Kind regards, > > > > > > Nuno Luz > > > > > > T?cnico de Suporte Inform?tico > > > > > > From mccalled at musc.edu Fri Mar 26 14:24:17 2021 From: mccalled at musc.edu (Mccalley, Daniel) Date: Fri, 26 Mar 2021 13:24:17 +0000 Subject: [Simnibs-discuss] Benefit of including diffusion tensors in modeling? Message-ID: Hi all, I think you may have published on this question, so feel free to forward the literature if that's easier -- but you find there to be a substantial difference in efield models when diffusion tensors are included in the modeling?
