TypeError: object of type 'NoneType' has no len() & NotADirectoryError:

• which operating system are you using?
  Windows 10,
• which environment is pyroSAR running in?
  python 3.6, spyder 4.1.3
• which version of pyroSAR are you using?
  0.12.1 one installed via pip or a clone of the GitHub repository? pip install
• which function of pyroSAR did you call with which parameters?

I used your example to create the *.xml file it works fine, I only changed the GRD item, and the path

from pyroSAR.snap.auxil import parse_recipe, parse_node

workflow = parse_recipe('blank')

read = parse_node('Read')
read.parameters['file'] = 'D:\pyrosar_test\S1A_IW_GRDH_----------------------------.zip' # I think not necessary which item is.

read.parameters['formatName'] = 'SENTINEL-1'
workflow.insert_node(read)

tnr = parse_node('ThermalNoiseRemoval')
workflow.insert_node(tnr, before=read.id)

bnr = parse_node('Remove-GRD-Border-Noise')
bnr.parameters['selectedPolarisations'] = ['VV'] 

workflow.insert_node(bnr, before=tnr.id)

write = parse_node('Write')
write.parameters['file'] = 'outname'
write.parameters['formatName'] = 'BEAM-DIMAP'
workflow.insert_node(write, before=bnr.id)

workflow.write('D:\pyrosar_test\outname_proc')
from pyroSAR.snap.auxil import gpt
gpt('D:\\pyrosar_test\\outname_proc.xml', 'D:\\pyrosar_test')

AND I tried up also,

gpt('D:\pyrosar_test\outname_proc.xml', 'D:\pyrosar_test')

• if applicable, which version of SNAP or GAMMA are you using in pyroSAR? SNAP 8
• the full error message

Then I used the *.xml which has been created in SNAP, it runs and I got the results I could open them, but gives this error,

from pyroSAR.snap.auxil import gpt

gpt('D:\\pyrosar_test\\spdivpy201524.xml', 'D:\\pyrosar_test')

Hi @falahfakhri-Iraq. Great you have found a workaround in the meantime! Yes, this is very similar to execute. I’ll post updates to the bug fixing in the next days…

The following works now:

import os
from pyroSAR.snap.auxil import parse_recipe, parse_node, gpt

workflow = parse_recipe('blank')

src = 'D:\\pyrosar_test\\S1A_IW_GRDH_----------------------------.zip'

outdir = 'D:\\pyrosar_test'
tmpdir = os.path.join(outdir, 'tmp')
outname = os.path.join(outdir, 'outname')
xmlfile = os.path.join(outdir, 'outname_proc.xml')

os.makedirs(outdir, exist_ok=True)

read = parse_node('Read')
read.parameters['file'] = src

read.parameters['formatName'] = 'SENTINEL-1'
workflow.insert_node(read)

tnr = parse_node('ThermalNoiseRemoval')
workflow.insert_node(tnr, before=read.id)

bnr = parse_node('Remove-GRD-Border-Noise')
bnr.parameters['selectedPolarisations'] = ['VV']

workflow.insert_node(bnr, before=tnr.id)

write = parse_node('Write')
write.parameters['file'] = outname
write.parameters['formatName'] = 'BEAM-DIMAP'
workflow.insert_node(write, before=bnr.id)

workflow.write(xmlfile)

gpt(xmlfile=xmlfile, cleanup=True, tmpdir=tmpdir)
