Unable to use MoMI-G on my own data

[LittleHannah]

Hi! Excellent work on MoMI-G.
I have a problem using MoMI-G. I am trying to use MoMI-G on my own data, and I am following the instructions in the manual, however, I have not been able to visualize my own data, the server keeps on showing the CHM1 demo. I would really appreciate it if you can help me with my problem, thx!

• I have created the static folder on the directory MoMI-G clones, it looks like this
  | -- config.yaml
  | -- GRCh38.json
  | -- HGDP01096.aug.gam
  | -- HGDP01096.aug.vcf
  | -- HGDP01096.aug.xg
• my config.yaml looks like this

  1 bin:
  2   vg: "~/.pggtools/bin/vg"
  3   vg_tmp: "vg"
  4   graphviz: "dot"
  5   fa22bit: "faToTwobit"
  6   bigbed: "bedToBigBed"
  7 reference:
  8   chroms: "GRCh38.json"
  9   data:
 10     - name: "hg19"
 11       features:
 12         - name: ""
 13           url: ""
 14           chr_prefix: ""

 33     static_files:
 34       - name: ''
 35         url: 'HGDP01096.aug.vcf'
 36         viz: ''

• My Docker.backend file looks like this

  1 FROM quay.io/vgteam/vg:v1.17.0 as build
  2 
  3 # backend container
  4 FROM momigteam/momig-backend
  5 
  6 COPY --from=build /vg/bin/vg /vg/bin/

  8 COPY static/config.yaml /vg/static/

 10 EXPOSE 8081

 12 CMD ["./graph-genome-browser-backend", "--config=static/config.yaml", "--interval=1500000", "--http=0.0.0.0:8081", "--api=/api/v2/"]

Thank you for trying MoMI-G. Instruction is here: https://momi-g.readthedocs.io/en/latest/quick_start.html#backend

Is it possible to change the backend URL from the MoMI-G public server to localhost?

$ sed -e "s/\"target/\"target_/g"  -e "s/\_target/target/g" -i.bak package.json
$ docker run --init -p 8081:8081 momigteam/momig-backend # Run it on another shell. It takes a little long time -- please wait.
$ yarn start

Also, is it possible to rebuild MoMI-G backend again after you modified Dockerfile.backend?

$ docker build -t momig-custom-backend -f Dockerfile.backend .
$ docker run --init -p 8081:8081 momig-custom-backend
