How do I install fieldtrip toolbox

I am trying to install the fieldtrip toolbox but it doesn't work.

I have followed the instructions on the fieldtrip webiste http://fieldtrip.fcdonders.nl/faq/should_i_add_fieldtrip_with_all_subdirectories_to_my_matlab_path but when I use addpath I keep getting a followig error message:

>> addpath Z:\EigeneDokumente\MATLAB\fieldtrip-20130129
Warning: Name is nonexistent or not a directory:
Z:\EigeneDokumente\MATLAB\fieldtrip-20130129 
> In path at 110
  In addpath at 87

What am I doing wrong and how do I install the fieldtrip toolbox (any toolbox?) in MATLAB?

Matlab tries to be very smart sometimes. Perhaps the '-' is interpreted as minus. Please try:

addpath('Z:\EigeneDokumente\MATLAB\fieldtrip-20130129')

and usually there is a space between "Eigene" and "Dokumente". But the error message actually looks like the '-20130129' part has been accepted as part of the string correctly.

If you are using MATLAB R2016a or later, you can do this without leaving MATLAB.

Whether you need additional toolboxes, apps, hardware support packages, or community submissions, you can easily browse and find what you’re looking for using the Add-On Explorer. Learn more here.

Add-ons extend the capabilities of MATLAB. Find add-ons for your task, no matter what you’re working on.

Try searching for "fieldtrip" from within the explorer!

How do I run it from here?

Answer 3

[Shashank Prasanna]

This is a 3rd party toolbox

You should probably contact: http://fieldtrip.fcdonders.nl/contact

To start with I would think you should check if "Z:\EigeneDokumente\MATLAB\fieldtrip-20130129" actually exists at all.

Thank you for your answers! It seems that it was the - problem cause now everything works ok.

how do i fix this error ft_definetrial(cfg); Warning: file or directory "ArtifactMEG.ds" does not exist, could not determine fileformat Warning: file or directory "ArtifactMEG.ds" does not exist, could not determine fileformat Warning: file or directory "ArtifactMEG.ds" does not exist, could not determine fileformat Warning: no trialfun was specified, using ft_trialfun_general evaluating trialfunction 'ft_trialfun_general' reading the header from 'ArtifactMEG.ds' Error using ft_read_header (line 202) file or directory 'ArtifactMEG.ds' does not exist

Error in ft_trialfun_general (line 84) hdr = ft_read_header(cfg.headerfile, 'headerformat', cfg.headerformat);

Error in ft_definetrial (line 178) [trl, event] = feval(cfg.trialfun, cfg);

You didn't download their example dataset called 'ArtifactMEG.ds'. Therefore, MATLAB could not access the file because it does not exist.
