This function added in version 0b7 is a function to analyze the most similar place by the Treasure map with the whole map by image matching. Execution of this is a high load of the CPU takes a while, and it is not something to be hit hardly.
If facets selected in advance do not match, false detection will obviously occur. The analysis fails unless you open the map at the default position (do not move the window). Because the UOSA client is difficult scaled, the hit rate drops below the UO2D client. UO2D refers to roughly the best place, but UOSA is somewhat shifted.
The analysis source image and the progress bar are displayed during analysis. When the black bar reaches the right side of the map, the analysis ends.
