Hi,
I read the following in the 2009 PNAS paper - "The networks were paired automatically by using spatial cross-correlation, with mean r = 0.53 (0.25:0.79); the weakest of these correlations thus has a significance of P < 10−5 (corrected). "
I wondered how the P value was calculated and if there are guidelines as to what r value would reflect a good correspondence between an 'in house' RSN and the PNAS maps ?
Cheers
