<font face="Helvetica, Arial, sans-serif">Newer versions of GRASS
use, by default, the ZSTD compressor. But, I believe that older
versions only support the simpler ZLIB.<br>
See here for details:<br>

<br>
In particular:<br>
"</font><font face="Helvetica, Arial, sans-serif">All GRASS GIS
raster map types are by default ZSTD compressed if available,
otherwise ZLIB compressed. Through the environment variable <tt>GRASS_COMPRESSOR</tt>
the compression method can be set to RLE, ZLIB, LZ4, BZIP2, or
ZSTD."<br>
<br>
So to make rasters in 7.8 and have them available in 7.2 you will
need to set the GRASS_COMPRESSOR environment variable in advance
to "ZLIB" before creating the rasters in version 7.8. THen those
should be readable in older versions.<br>

Dear List,
<div class=""><br class="">
</div>
<div class="">I am running MacOS High Sierra (10.13.6) and have
been using various versions of Grass GIS. Recently, I prepared
raster maps using 7.8.3 but these maps do not open in lower
versions of Grass such as 7.2.2. Higher versions like 7.9 open
the same raster images without a problem.</div>
<div class=""><br class="">

<div class="">I am getting the error below:</div>

<div class="">I will greatly appreciate any advice on fixing this
issue for pre 7.8 versions of Grass.</div>
