imageMath.py error

[bigfollower]

when I using fringe,imageMath.py have a error---TypeError:%d format:a number is required,not NoneType.How can I solve it?

[ehavazli]

you need to run
gdal2isce_xml.py -i ampdispersion/ampdispersion
this will create the required xml file.

你需要运行 gdal2isce_xml.py -i ampdispersion/ampdispersion 它来创建所需的 xml 文件。

I have solved this problem, there is another trouble.
Why is the Coherence file required for mintpy not generated after fringe is run?
