I seem to be having a problem downloading the R package spatialLIBD. The problem seems to occur with the magick dependency... I don't have root access so cannot install Magick++. I am only interested in getting the datasets, not using the visualization functions.... is there a work around to installing spatialLIBD without having to this dependency?

# include your problematic code here with any corresponding output

Hi @kstern,

Thank you for your interest in spatialLIBD. You will still need the package in order to re-cast the object into a SpatialExperiment object (this package didn't exist when we made spatialLIBD). Thus, I strongly encourage you to reach out to whomever has root access in your system to install the magick dependency. Since you are using Ubuntu 20.04.4, it should be straight forward for your systems administrator to install it.

Otherwise, you can dive into the internals of the package at https://github.com/LieberInstitute/spatialLIBD. Namely https://github.com/LieberInstitute/spatialLIBD/blob/master/R/fetch_data.R and https://github.com/LieberInstitute/spatialLIBD/blob/master/R/sce_to_spe.R. But we don't encourage this option.

Another option is to use http://bioconductor.org/help/docker/ which does include the magick dependency.

Best, Leo

(As for ExperimentHub, we have it all ready but haven't uploaded the data yet to a non-Dropbox location in order to make this work https://github.com/LieberInstitute/spatialLIBD/blob/30204438ba07e463ee65af828f40af4de3c3a429/R/fetch_data.R#L126-L129. We'll do so in the coming month or so. Otherwise, you could use ExperimentHub alone to access the data, but you'd still need spatialLIBD to cast it to SpatialExperiment)
