Maxfilter Version 2.2

Brief [http://imaging.mrc-cbu.cam.ac.uk/meg/maxintro introduction and literture].

Example

Version 2.2. is currently the default when using the "maxfilter" command at the CBU.

This command will apply Maxfilter including Signal Space Separation (SSS), its temporal extension (ST), and movement compensation.

maxfilter  -f input_file.fif  -o output_file.fif  -st  -origin 0 0 45  -frame head  -autobad on  -movecomp  -format short  -force 

For more information on these and other options, see the [attachment:Maxfilter_Manual2.2 Maxfilter 2.2 Manual].

Known problems and bugs

Maxfilter 2.2. cannot do downsampling and filtering at the same time as movement compensation. You will therefore have to run those in a separate step, e.g.

maxfilter  -f input_file.fif  -o output_file.fif  -ds 4  -lpfilt 40

Diagnostics

You can get information about movement parameters using these [http://imaging.mrc-cbu.cam.ac.uk/meg/maxdiagnost scripts to analyse maxfilter output].
