However, I solved the problem using GDAL's algorithm "Clip raster by mask layer" and by seting the option "Keep resolution of output raster" to "Yes". That produced a .tif file with equal pixel size (200, -200).<br>
<br>
Following, I convert this GeoTIFF to .ASC format using: "Raster > Conversion > Translate (Convert format)" and the setting the Output file to [GDAL] Arc/Info ASCII Grid (*.asc *.ASC).<br>
<br>
The result is three files: the auxiliary file .aux, the coordinate system file .prj, and one more filename of File type FILE that can be opened with Notepad. Disappointingly, no .asc file was created. What am I doing wrong? I need .asc files of my environmental variables to be later processed using other software.<br>

Thanks!<br>

Hi, seems that you have an older version of PROJ library. Did you download<br>
the package or install via homebrew? I recommend the latter (but you should<br>
use command line), I followed this<br>
<<a href="https://github.com/OSGeo/homebrew-osgeo4mac/wiki/Developing-on-QGIS-using-OSGeo4Mac" target="_blank">https://github.com/OSGeo/homebrew-osgeo4mac/wiki/Developing-on-QGIS-using-OSGeo4Mac</a>><br>
guide and everything is fine, same OS and version of QGIS.<br>

I delete old version first but I can't open new version when finishing the<br>
installation. I got this message: Qgis can't be open due to a problem.<br>
<br>
Any idea? Thanks<br>
Jesus<br>
