AccessMod has been developed to carry out the various analyses as quickly as possible. However, if you are working with large data sets, due to for example to the high-resolution of the raster data sets and/or a high number of health facilities, analyses can take a long time. As a result, it may seem that nothing is happening while AccessMod is working on the back. Usually, in this case, if you don't see an error message on screen, this means AccessMod is still running in the background.
If you want to run an extensive analysis, it is recommended to first ensure that a large amount of memory is available on your computer. It is recommended to have at least 8GB of memory in such cases.
