Hi all,

On the Phenotypic key document says that handedness is codified as 0 left, 1 right and 2 ambidextrous. However, taking a look at the phenotypic info of NYU database I see that the values on handedness go from -0.11 to 1 and on the neuroimage database one of the subjects has a value of 3 on handedness. Is there any other doc that explains how this values were codified?

Thanks in advance

Hi Susanna, 

Sorry for the slow response. The values for NYU are based on the Edinbugh Handedness Inventory. It ranges from -1 to 1, with -1 being strong left-handed and 1 being strong right-handed.

The 3 in the neuroimage database is a type from recoding, it should be 2 (i.e. ambidextrous).

Hope this clarifies things!
