Data Availability

Where can I find seqFISH+ and other ready-to-use datasets?

Checkout our GiottoData extension package to find already preprocessed datasets and Giotto mini Objects.

Where else can I find more spatial datasets?

Checkout the following for more spatial -omics data:

• Aquila

• Tencent’s SODB

  • PySODB, a python interface for the SODB

How can I automatically download tutorial datasets?

Use getSpatialDataset() from GiottoData:

# Ensure Giotto Suite is installed
if(!"Giotto" %in% installed.packages()) {
  devtools::install_github("drieslab/Giotto@suite")
}
library(Giotto)

# Ensure Giotto Data is installed
if(!"GiottoData" %in% installed.packages()) {
  devtools::install_github("drieslab/GiottoData")
}
library(GiottoData)


# choose your directory
my_working_dir = getwd()

# merFISH example:

# standard download data to working directory
getSpatialDataset(dataset = 'merfish_preoptic', directory = my_working_dir)

# use wget to  download data to working directory (much faster)
getSpatialDataset(dataset = 'merfish_preoptic', directory = my_working_dir, method = 'wget')

# avoid certification issues with wget
getSpatialDataset(dataset = 'merfish_preoptic', directory = my_working_dir, method = 'wget', extra = '--no-check-certificate')
