<div><br></div>Regarding this question I decided to delete, using g.remove, all lists that I have created. And I was sucesseful but, anytime I open, using wxpython menu, i.group, the following is displayed in COmmand output:<div>
<div>Invalid element 'gr03@landsat@landsat'</div><div>Invalid element 'gr04@landsat@landsat'</div><div>Invalid element 'gr05@landsat@landsat'</div><div>Invalid element 'gr06@landsat@landsat'</div>
<div>Invalid element 'gr07@landsat@landsat'</div><div>Invalid element 'gr08@landsat@landsat'</div><div>But, these groups are no longer Available...</div><div><br></div><div>Any tips? or maybe some Module/library that I'm missing?</div>

<p>I have re-downloaded NC_spm_08 from GRASS website and the already available group, <a href="mailto:lsat7_2000@landsat" target="_blank">lsat7_2000@landsat</a> doesn't display sub-group in i.cluster or other functions..</p>
<div>Nevertheless, I tried what Markus said:</div>
<div>i.group group=t02 subgroup=sub input=lsat5_1987_10,lsat5_1987_20 (altough this is not performed by GUI but by me on the command output)</div>

Adding raster map <<a href="mailto:lsat5_1987_20@landsat" target="_blank">lsat5_1987_20@landsat</a>> to subgroup<br>i.group complete.</div>
<div> </div>
<div>And then at i.cluster when I select t02, in subgroup there is no sub-group only "NOT SELECTABLE ELEMENT".</div>
<div> </div>
<div>What am I missing/or might be wrong?</div>

Could you retry to make the group etc in the landsat mapset itself in<br>order to understand if @landsat makes the difference?<br><font color="#888888"><br>Markus<br></font></blockquote><br>
