The markers database has moved to a new location.
This will NOT get automatically downloaded. The automatic download will not work until we release a code fix.
You can download the markers from the following link for now and extract to the location of your choice. By default, PhyloSift will look in the following directory ~/share/phylosift. This path can be modified in the phylosiftrc file.

Sorry for the inconvenience.
