Hi Xiaohua,
I update my gmtsar version.
When I run it with the SAR data (The SAR data cover the 2017 M7.6 Melinka earthquake, Chile (Melgar et al., 2017, EPSL), where the land is separated by the sea.), there meets a problem about the snaphu command.
Is the number of the node too big?
Could you help me? Thanks!
