The locations, coordinates of the locations and collection season are also displayed in Additional file 2: Table S2.
This produces a sequence of stops, each one with a centroid calculated as the median of the locations coordinates, and a duration equal to the time between the last location and the first location sample.
To some extent, it is robust against scale changes, because all values are normalized by the size of the object, and against rotation when the locations coordinates p uv are replaced by the distance to the center of the bounding box.
To transform the source locations coordinates into Talairach coordinates, the most anterior and posterior points of the sphere, the most left and right points of the sphere, as well as the most superior and inferior points of the sphere were coregistered with the normalised brain, thereby transforming the sphere into an ellipsoid approximating the shape of human brain.
We also included spatial information in the database: Exact locations (coordinates) of each respondent's home, as well as respondent's socioeconomic information and general information about the residential buildings (e.g. year of construction, size of the residence) were obtained from the FPRC.
These sources were modeled as equivalent current dipoles, which were superimposed on an MRI of a standard brain in MNI space (Fig. 1), whose prior mean locations coordinates (x, y, z) are: bilateral ITC: −43, −54, −15 (left); 43, −54, −15 (right); bilateral MTL: −27, −15, −20 (left); 27, −15, −20 (right); and bilateral IFC/VLPFC: −54, 35, 6 (left); 54, 35, 6 (right).
The Nikon D2X, the company's current top-of-the-line SLR model ($5,100), works with an optional MC-35 GPS Adapter cord ($139) that connects with a standard G.P.S. receiver (which you must also buy) to automatically save location coordinates with each photograph.
Location coordinates and elevation for each station are also given.
Let the pair (x,y) reflects location coordinates.
Sample size, location, coordinates, and voucher specimens are indicated.
The specific location coordinates are listed in Table 4.
