<div dir="ltr"><div>Hi,<br><br></div><div>My name is Francesco and I'm very new with GRASS. <br></div><div>I tried to use the i.segment command and I got a problem.<br></div><div>The command lines I used are the following:<br>
<br>i.segment -d group=060140_file_OFD output=060140_file_segs_L1 threshold=0.1 <br>i.segment -d group=060140_file_OFD output=060140_file_segs_L2 threshold=0.2 seeds=060140_file_segs_L1 min=2<br><br></div><div>the lines are very similar to the example provided in the tutorial:<br>
<br></div><div><a href="http://grass.osgeo.org/grass70/manuals/i.segment.html">http://grass.osgeo.org/grass70/manuals/i.segment.html</a> <br><br></div><div>Anyway, when I run the second line, the output window return the following message:<br>
<br></div><div>WARNING: Region consists of only one cell, nothing to update <br><br></div><div>and the process doesn't run.<br></div><div>I tried to change the parameters, but the result was always the same.<br><br></div>
<div>What is my mistake?<br><br></div><div>Thank you!<br><br></div><div>Francesco<br></div><div><br><br><br></div><div><div><div><div dir="ltr"><div><div><div><div>_______________________________________________________<br>
