findpaths function output nearly empty files

[JianmeiZhong]

Hello, I ran findpaths funtion with imputed 10x matrix according to the example with no error before this step.But the 2 generated files in results\paths\SP_46.SP_* are nearly empty.CellRouter.sh file are complete but executed unsuccessfully with "running command './CellRouter.sh' had status 127" in Rstudio with R 3.4.3 version.Any idea to this issue?

Thanks in advance, Jianmei Zhong
