matrix format: 255*255*28

255 exporting countries
255 importing countries
28 years (from 1986 to 2013)

output data are split into FLOWS and TOPOLOGY

FLOWS
trade estimates are provided with RAS and GRAVITY

"exante" means that trade is estimated considering a unique matrix whose elements represent the trade flows in dollar pertaining to the 5 study crops;
"expost" means that trade is primarily estimated for single crop matrix and then is aggregated across crops using dollars as weights

TOPOLOGY
the estimates of the adjacency matrices are provided for both RAS and GRAVITY

"adj_reconstr_" contains the estimated adjacency matrix obtained for a given threshold as specified in the manuscript

"missed" contains the percentage of missed relations calculated with respect to the total number of real active relations

"spuri" contains the spurious relations calculated with respect to the total number of possible relations

"numero_link" contains the number of active links according to the model

"perc_flusso_catturata" contains the percentage of real flow that is preserved along the estimated trade relations
