I am trying to export layers from an analysis using raster calculator in ArcGIS. I have 6 files, all have the same extent, cell size and number of rows and columns. I have tried exporting (RASTER TO ASCII) individually as well as tried batch exporting. However, when I import into MATLAB to run my statistical analysis, the imported files have different numbers of columns and rows. Any idea how to solve this? Or whether this sounds more like a GIS issue or Matlab issue?
