SNAPHU could not excute

Dear Frieds
I use S1 for interferometry and when I excute snaphu I got error as :slight_smile:
snaphu v1.4.2
26 parameters input from file snaphu.conf (84 lines total)
only one tile–disregarding multiprocessor option
Reading wrapped phase from file Phase_ifg_VV_05Jan2023_22Feb2023.snaphu.img
No weight file specified. Assuming uniform weights
Reading correlation data from file coh_IW2_VV_05Jan2023_22Feb2023.snaphu.img
Can’t open file coh_IW2_VV_05Jan2023_22Feb2023.snaphu.img
Abort
can anypne tell me why?
