ABout replacing docker

Hi R-FMRI team,

Hope you are doing well and  thanks for the wonderful effort at processing pipelines software. 

I do have a question regarding removing the non-brain tissues(Bet process), and I am getting error of docker command not found.

For various reasons we cannot install docker on the server. but we can use singularity for containers. Can I know which parts need to update in the Matlab code with using singularity

I have one more question, will be large result differece in the rs-fmri network study without runing the Bet process? 

Can I know how to evulate the preprocessing result from the DPARSF A. 

Thank you.

-Jin.
