Web ResourcesBR

Below is a list of web resources used in the talk BR

[attachment:HensonSPM06.pdf Henson SPM 06]BR

• Rik Henson's article. Also on the imaging wiki.

[attachment:Stochastic.pdf Stochastic Designs]BR

• This is one of the old Friston papers looking at stochastic designs in event related designs. It has a clear explanation of efficiency that is worth a read.

[attachment:TradeOff.pdf Liu Trade-off Paper]BR

• Thomas Liu's article on the fundamental trade-offs between estimation and detection. Must read.

[attachment:GeneticAlgorithms.pdf Tor Wager's article on Genetic Algoirthms]BR

• The background on efficiency issues is worth a read even if you are not interested in Genetic Algorithms.

See also DesignEfficiency pages on the imaging wiki.

ToolsBR

• Genetic Algorithm SPM toolbox (Tor Wager)

[http://www.fil.ion.ucl.ac.uk/spm/ext/#Design_Magic SPM colinearity toolbox] BR

• SPM toolbox for assessing collinearity (Matthijs Vink)

See SharedCode for a short script that allows you to check your own design efficiency.
