I started using a mask to eliminate most of the matrix, to see if that helped. It did not, so I started the process again in i.segment but with the previous segmentation output as seed to reduce processing. This time I also got an error with i.segment in 2 attempts with different parameters. I looked for documentation, but I couldn't find any solutions and I rather not mess with the scripts. I do get a raster-output which looks ok, but i.segment.stats fails to create an attribute table for further analyses. My questions are: Is the area too big (too much pixels)? Are there too many segments? The count of the last output is 9054 segments. Or should I start the process again form the beginning without the seed assuming the Mask is not the problem? The processing might take several weeks though. <br>><br>> i.segment error:<br>> ERROR: Region of size 501508 should be in search tree<br>><br>> i.segment.stats errors:<br>> ERROR: Error while executing: 'CREATE TABLE segmstat_tmp_vect_7968 (cat int, area double precision, compact_circle double precision, DV2_mean double precision, DV2_stddev double precision, DV2_variance double precision, DV2_coeff_var double precision, DV2_first_quart double precision, DV2_median double precision, DV2_third_quart double precision, DV2_perc_90 double precision, DV4_mean double precision, DV4_stddev double precision, DV4_variance double precision, DV4_coeff_var double precision, DV4_first_quart double precision, DV4_median double precision, DV4_third_quart double precision, DV4_perc_90 double precision, IDM2_mean double precision, IDM2_stddev double precision, IDM2_variance double precision, IDM2_coeff_var double precision, IDM2_first_quart double precision, IDM2_median double precision, IDM2_third_quart double precision, IDM2_perc_90 double precision, IDM4_mean double precision, IDM4_stddev double precision, IDM4_variance double precision, IDM4_coeff_var double precision, IDM4_first_quart double precision, IDM4_median double precision, IDM4_third_quart double precision, IDM4_perc_90 double precision, W2_mean double precision, W2_stddev double precision, W2_variance double precision, W2_coeff_var double precision, W2_first_quart double precision, W2_median double precision, W2_third_quart double precision, W2_perc_90 double precision, DV4_mean double precision, DV4_stddev double precision, DV4_variance double precision, DV4_coeff_var double precision, DV4_first_quart double precision, DV4_median double precision, DV4_third_quart double precision, DV4_perc_90 double precision, neighbors_count double precision, area_nbrmean double precision, area_nbrstddev double precision, compact_circle_nbrmean double precision, compact_circle_nbrstddev double precision, DV2_mean_nbrmean double precision, DV2_mean_nbrstddev double precision, DV2_stddev_nbrmean double precision, DV2_stddev_nbrstddev double precision, DV2_variance_nbrmean double precision, DV2_variance_nbrstddeGRASS_INFO_ERROR(7020,1):<br>> Traceback (most recent call last):<br>> File "C:\Users\haarlooj\AppData\Roaming\GRASS7\addons/scri<br>> pts/<a href="http://i.segment.stats.py" target="_blank">i.segment.stats.py</a>", line 370, in <module><br>> main()<br>> File "C:\Users\haarlooj\AppData\Roaming\GRASS7\addons/scri<br>> pts/<a href="http://i.segment.stats.py" target="_blank">i.segment.stats.py</a>", line 357, in main<br>> gscript.run_command('db.execute', input=insert_sql,<br>> quiet=True)<br>> File "C:\Program Files\GRASS GIS<br>> 7.4.0\etc\python\grass\script\core.py", line 421, in<br>> run_command<br>> return handle_errors(returncode, returncode, args,<br>> kwargs)<br>> File "C:\Program Files\GRASS GIS<br>> 7.4.0\etc\python\grass\script\core.py", line 332, in<br>> handle_errors<br>> returncode=returncode)<br>> grass.exceptions.CalledModuleError: Module run None<br>> ['db.execute', '--q', 'input=Z:\\GRASS_GIS\\Cottica_LUP\\LUP<br>> 1\\.tmp/unknown\\7968.1'] ended with error<br>> Process ended with non-zero return code 1.
