So, we solved the problem by setting the processing extent to the shapefile. However, we want to iterate 317 shapefiles from a file geodatabase within a model. In this model, we can't get the processing extent option to match the iterating files. Does anyone have a suggestion how to do this? So we need the processing extend in the 'extract by mask' tool to match the iterating files from the file gdb to prevent us from having to do all the 317 files by hand. See the attachment for a visual (and better) explanation of the problem and the display of our model.

I have tried several options of processing extent now but none have the desired effect. To clarify; the method (so without Processing Extent checked) works perfectly on LGN5. Each masked patch of land gets its own specific amount of rows and columns. We looked at the Clip tool but we found that that tool caused overlap in de data. In case the mask doesn't work out; could the overlap of data by using clip be avoided by setting the snap raster to LGN6?

Thank you for your reply! I've looked at it but it isn't checked. Not the 'Extent' nor 'snap raster' options. We havn't changed any other settings than switchin maps so there has to be something different with the map i suppose...?

Reader, We are working on a landuse map from the Netherlands (LGN6) which we extract by mask bassed on several polygons. However the colomns and rows in the new (masked) maps, which are only a small part of the original LGN6 data, addapt the original size in colomns and rows. Even when zooming to layer it shows the area of the full (original) map and not just the masked area. We used this method on other map data (soil and LGN5) which don't show this problem. This is a big problem because we can not analyse our LGN6 data in FRAGSTATS. Any idea on what to look at? regards, Jelle H. (LGN6&soil map: Alterra, 2007/2007 & Alterra 2000)
