Planner is a software that assists in MR-guided electrophysiology. It was designed by Shay Ohayon, a grad student in the Tsao lab. The software enables easy visualization of the target site and allows the user to place virtual chambers, grids, and electrodes with different designs. It can also find optimal trajectories by finding the optimal grid hole, rotation and tilt angle. The other key feature of this software is its ability to automatically solve the registration problem between MR space and stereotactic space. It can report the stereotactic parameters needed to place the manipulator’s tip and align it with the planned chamber position in any desierable direction:
Recently, we added a new feature that allows to design custom grids with each grid hole going in arbitrary direction. Such grids can be automatically exported as a Solidworks model and printed on a high end 3D printer (Projet).

Operating System: Windows XP/Vista (32 or 64 bit), Linux (64 bit only), Mac (64 bit only)
Matlab: Should be compatible with R2009b and later verions
Solidworks: If you are planning to print custom grids using the grid export function, make sure you are running with Windows 64 bit. Solidworks 2011, 2012 and 2013 are supported.
Memory: Although you can probably run planner with as little as 1G of RAM, it is usually preferred to have at least 4G. The more volumes you load, the more memory will be required.
Screen Resolution: At least 800 vertical pixels. If you are running on a windows laptop with 1200×800 (or similar), move the taskbar location to the left.
CPU: No real requirement here, but you probably want Core 2 Duo or stronger
Graphic card: If you plan to visualize surfaces, a good graphics card is required (nVidia Geforce/Quadro)
1. Unpack the compressed file somewhere.
Window users: add a system environment variable (Start->Control Panel->System->Edit the system environment variables)
Value: C:\\MATLAB\\R2009b_x64\\bin\\win64\\MATLAB.exe (modify this to where you installed matlab)
use Runme_x64.bat to run planner
If you are using 32 bin version, add this variable:
Value: C:\\MATLAB\\R2009b_x32\\bin\\win64\\MATLAB.exe (modify this to where you installed the 32-bit version of matlab)
use Runme.bat to run planner
use runme.csh to run planner (assuming matlab is already in the path)
