I've been using the localization module with my own png map and log file. The log file was generated using data from Cogmation's robotSim. There are no problems reading the data but I get an error once localization starts--assertion failed in ktlocalizer\probabilitygridmodel. I feel that the problem could lie in my pose input. Does the z axis increase as you go down or up the map?

If you are using your own PNG map, you need to insert in the metadata in the PNG for karto to know about. See the other article.I have a question about the format you use to save the png maps.I think you are saving some extra information in the heather of the PNG map file that specifies the resolution of the map. The thing is that, if we modify the png map file by using an image editor or else, this information is no longer saved.My question is: is it true that are you saving such information?. How can I save that too from my own program in order to 'repair' an edited map file?
