`gtrack.2d.import()` Cannot create track.

[jiangpuxuan]

Here is my code:

gtrack.2d.import(
  track=my_track_name, 
  description="observed hic data", 
  file=c(my_shaman_data))

gdb.reload()

The error is :

Error: Cannot create track at /usr/local/lib/R/site-library/misha/trackdb/test/tracks/grnsmile_hic_obs.track: Permission denied

I am not a sudo user , so I cannot create a certain file in the path /usr/local/lib/R/site-library/misha/trackdb/test/tracks/.....
So is it necessary to have sudo authority in gtrack.2d.import() ?

Thank you for your help!

Hi @jiangpuxuan,

I think you are trying to create a track in the examples database, in which you do not have sufficient permissions. I suggest you first create a misha database for the desired genome, see examples here:

https://tanaylab.github.io/shaman/articles/import.html#create-misha-database-from-ucsc

then, set the root to your newly created database with gsetroot and create your 2D track.

Oh, I solved it by change the path. Thank you for your help!
