Moving data to your instance from the data store¶
Some data has been pre-downloaded for you and stored on the CyVerse data store in order to help expedite your projects.
While you CAN access that data directly on the data store, it is HIGHLY recommended that you copy the data over to your instance (see "Cyverse data management" under "Collaborating on the cloud" for more information). This is because your work with the data will be dramatically faster with it located on your instance.
Take, for instance, the treemap data.
If we load and plot the data without moving it, it takes just a few seconds (i.e. ~2.973 seconds). Not bad.
require(terra)
require(tictoc)
tictoc::tic()
treemap <- terra::rast("~/data-store/data/iplant/home/shared/earthlab/forest_carbon_codefest/TreeMap/treemap2016_southernrockies.tif")
terra::plot(treemap)
tictoc::toc()
However, if we load and plot the data after moving it, it takes less than a second (i.e. ~0.302 seconds). Even better! This 10x increase in speed will add up incredibly quickly as soon as you start working more intensively with the data.
require(terra)
require(tictoc)
system("cp -r ~/data-store/data/iplant/home/shared/earthlab/forest_carbon_codefest/TreeMap ~/TreeMap") #move the data first!!
tictoc::tic()
treemap <- terra::rast("~/TreeMap/treemap2016_southernrockies.tif")
terra::plot(treemap)
tictoc::toc()
Takeaway: seriously, just copy the data over.
