Hello everyone, I try to do this map…but i don’t receive a good resolution… This is my code : ```auto gmt begin ETNA pdf,png gmt set IO_COL_SEPARATOR=tab gmt coast -R14.19816/15.31768/38.30667/38.82758 -Wthin -JM5i -Baf -Gbisque -Sskyblue -Df -I1 gmt grdimage @earth_relief_01s -R14.19816/15.31768/38.30667/38.82758 -I+d gmt inset begin -DjBL+w2c -M0 -F+gwhite+p1p gmt grdimage @earth_relief_01m -R11.50000/16.00000/35.39997/39.0000 -I+d gmt inset end gmt end show ``` and i receive this error: ```auto grdblend [ERROR]: Failed to remove C:\Users\Anna\AppData\Local\Temp/grdblend_resampled_13220_2.nc! [remove error: Permission denied] grdblend [ERROR]: Failed to delete file C:\Users\Anna\AppData\Local\Temp/grdblend_resampled_13220_2.nc ``` The inset have a good resolution and i don’t have error! For the principal map, i receive this error ---

It seems GMT is not allowed to modify the working directory, which is odd. I tried your command and got the following : ```auto gmt [WARNING]: File /Users/guillaume/.gmt/server/gmt_hash_server.txt said it has 182 records but only found 176 - download error??? gmt [WARNING]: File /Users/guillaume/.gmt/server/gmt_hash_server.txt will be deleted. Please try again gmt [WARNING]: File /Users/guillaume/.gmt/server/gmt_hash_server.txt.old said it has 181 records but only found 175 - download error??? gmt [WARNING]: File /Users/guillaume/.gmt/server/gmt_hash_server.txt.old will be deleted. Please try again grdblend [NOTICE]: Remote data courtesy of GMT data server oceania [http://oceania.generic-mapping-tools.org] ``` So maybe a bug with GMT server ? @maxrjones ? ---

OK thanks, but what should I do? Is this something I can solve? ---

What does the principal map look like? White? The error message only says that it was unable to delete the file. ---

the base map is created with the costa command. Do I have to delete it? ---

Yes, of course. The coast is plotted anyway (by the way, when you succeed plotting the grid, it will overlay your coast lines). No, you don’t have to delete it. I’m not sure whats wrong with the file permission stuff. ---

> [@Andreas](#): > > No, you don’t have to delete it. I’m not sure whats wrong with the file permission stuff. This clearly looks like a bug that was fixed after 6.3.0 but one that does not affect anything. Just annoying to see a message saying _ERROR_ ---

so I don’t have to modify anything? or is it just a problem with the grid overlay that’s not right? have i done it wrong? or haven’t i done it at all… ---

Apparently this was a bug which now is fixed. You have to wait until a new version is released, or build from source. ---

okay, thanks for the answer. what means “build from source”? How do it? ---

It means that you build gmt from source code to create executable files. When you install gmt this has already been done for you. If youre new to programming and that sort of stuff, it’s quite a steep learning curve. If you want to give it a try, see [Building GMT](https://github.com/GenericMappingTools/gmt/blob/master/BUILDING.md). I would recommend you to wait for the next release instead. ---

That bug is innocuous. Just a little bit annoying but the error message can be safely ignored.
