This error is now fixed in trunk, relbr76, and relbr74 (r73512-4) Markus M > > On Thu, Oct 4, 2018 at 4:07 PM Markus Metz <markus.metz.gisw...@gmail.com> wrote: >> >> Can you please try with GRASS 7.6 64 bit [0] and report if the error still persists or not? >> >> Thanks, >> >> Markus M >> >> [0] https://wingrass.fsv.cvut.cz/grass76/x86_64/ >> >> On Thu, Oct 4, 2018 at 5:07 PM Jamille Haarloo <j.r.haar...@gmail.com> wrote: >> > >> > Dear Grass community, >> > >> > I have been experimenting with i.segment, i.segment.uspo and i.segment.stats on relatively small areas of a worldview-2 image. >> > After some success I tried i.segment and i.segment.stats on the entire area of 19875 ha, but I kept getting the same errors with i.segment.stats. 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. >> > >> > i.segment error: >> > ERROR: Region of size 501508 should be in search tree >> > >> > i.segment.stats errors: >> > 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): >> > Traceback (most recent call last): >> > File "C:\Users\haarlooj\AppData\Roaming\GRASS7\addons/scri >> > pts/i.segment.stats.py", line 370, in <module> >> > main() >> > File "C:\Users\haarlooj\AppData\Roaming\GRASS7\addons/scri >> > pts/i.segment.stats.py", line 357, in main >> > gscript.run_command('db.execute', input=insert_sql, >> > quiet=True) >> > File "C:\Program Files\GRASS GIS >> > 7.4.0\etc\python\grass\script\core.py", line 421, in >> > run_command >> > return handle_errors(returncode, returncode, args, >> > kwargs) >> > File "C:\Program Files\GRASS GIS >> > 7.4.0\etc\python\grass\script\core.py", line 332, in >> > handle_errors >> > returncode=returncode) >> > grass.exceptions.CalledModuleError: Module run None >> > ['db.execute', '--q', 'input=Z:\\GRASS_GIS\\Cottica_LUP\\LUP >> > 1\\.tmp/unknown\\7968.1'] ended with error >> > Process ended with non-zero return code 1.
