Homer makeTagDirectory error with hg19

[micron]

I have installed hg19 for homer but when I try to make a tag directory:

makeTagDirectory my_tagDirectory -checkGC -genome hg19 -format bed myfile.bed

I get the following error messages:
Couldn't open a sequence file for "1" (home/user/glob/homer//data/genomes/hg19//genome.fa.masked)

...and so on for every chromosome.

I tried giving homer the genome in a separate fasta file, and then it works.

Any tips on what might be the problem?
