[MSNoise] Issue-regarding Grid.dat

Dear All, Can any one of you help me out. prepare_tomo.py is writing "Grid.dat", However, it seems it is writing wrong minlat and minlon. In place of longitude it seems it is writing latitude. Station coordinates are correct in STACoord.dat. How X and minlon = df[3].min() - xstep*1.5 maxlon = df[3].max() + xstep*1.5 minlat = df[2].min() - ystep*1.5 maxlat = df[2].max() + ystep*1.5 f.write("%f %f\n"%(minlon, maxlon)) # It is writing latitude f.write("%f %f\n"%(minlat, maxlat)) # It is writing longitude f.write("%f %f\n"%(xstep, ystep)) f.close Somehow in the final tomographic plots (result_*), I am getting a a mirror image of expected image. (Latitude in x-axis and Longitude in Y-axis). If I change Grid.dat manually (by changing lat and lon) before running ANSWT.py, it is not working well. Regards, arun
