[GRASS-user] parse_command r.gwr with -e flag

Hi all,
I want to parse the command r.gwr using python scripting (parse_command). I can parse all the results without any problem as shown below…

bw=g.parse_command(‘r.gwr’,mapx=(‘B1’,‘B2’), mapy=‘B3’, estimates=‘tmp_bathymetry’, residuals=‘residual’, bandwidth=10, overwrite=True)
Calculating average…
100%
Geographically weighted regression…
100%
bw
{u’‘: None, u’bmean1’: u’0.00326378’, u’bmean0’: u’173.645’, u’Rsq1’: u’0.0024281’, u’bmin2’: u’-1.17172’, u’bmin1’: u’-1.5533’, u’bmin0’: u’-13376’, u’bmax1’: u’3.42206’, u’bmax0’: u’6829.21’, u’AIC’: u’38512.1’, u’bmax2’: u’2.15423’, u’AIC2’: u’45268.2’, u’AIC1’: u’39181.4’, u’BIC’: u’38531.5’, u’Rsqadj’: u’0.984456’, u’bstddev2’: u’0.628214’, u’bstddev0’: u’3798.71’, u’bstddev1’: u’0.552098’, u’BIC2’: u’45272.7’, u’Rsq’: u’0.984463’, u’BIC1’: u’39185.9’, u’F’: u’146367’, u’Rsq2’: u’0.0514878’, u’bmean2’: u’0.859825’, u’F1’: u’722.008’, u’F2’: u’15310.1’, u’predictor2’: u’B2’, u’predictor1’: u’B1’, u’AICc1’: u’39181.4’, u’AICc2’: u’45268.2’, u’n’: u’4623’, u’AICc’: u’38512.1’}

But I cannot parse the optimal bandwidth when I use ‘-e’ flag which is only printing on the screen as shown below …

bw=g.parse_command(‘r.gwr’,mapx=(‘B1’,‘B2’), mapy=‘B3’, estimates=‘tmp_bathymetry’, residuals=‘residual’, bandwidth=10, flags=‘eg’,overwrite=True)

Hi,

I updated the source code, so if you reinstall it, it should work. You
have to call it together with -g flag.
