We would appreciate it to be mentioned in your publication if you have used FieldTrip for a considerable part of your analysis.

Please cite the FieldTrip Reference Paper when you have used FieldTrip for data analysis in your study.

Besides referring to the paper, you can use a phrasing like this, where REF corresponds to the reference to the paper.

• The data analysis was performed using the Fieldtrip toolbox for EEG/MEG-analysis (REF; Donders Institute for Brain, Cognition and Behaviour, Radboud University Nijmegen, the Netherlands. See http://www.ru.nl/neuroimaging/fieldtrip).

• The data analysis was performed using the Fieldtrip toolbox for EEG/MEG-analysis, developed at the Donders Institute for Brain, Cognition and Behaviour (REF; http://www.ru.nl/neuroimaging/fieldtrip).

• The data analysis was performed using Fieldtrip (REF; http://www.ru.nl/neuroimaging/fieldtrip).

Important is that you refer to the correct web address, so not to "www2.ru.nl" and not to "fieldtrip.fcdonders.nl", but to "www.ru.nl/neuroimaging/fieldtrip".
