Error in_AnalyzeRepeats in Homer

Hi, below is my command for analyze repeats using homer:

analyzeRepeats.pl rna hg38 -count genes -d A1 A2 H4_hg38_UCSC -noadj > OutputA1A2A3H4.txt

Tag Directories:
    A1
    A2
    A3
    H4

Can't find genome "hg38"...
    Assuming hg38 is the name of the orgaism (or use "none")

!!! Can't use "repeats", "rna", or "miRNA" as input file if you don't use a valid homer genome

I am getting errors and the command seems to not be working How do i solve it? Kindly help, Many thanks in advance!

It seems you have not yet installed the hg38 reference genome. Run perl /path-to-homer/configureHomer.pl -install human and/or consult the section Updating Genomes and Genomic Annotations from the UCSC Genome Browser (i.e. Genome packages) in this manual.

Dear Matthias,

Thanks very much for your reply, it now works & initiated running. But, now it gives another error "could not open tagInfo.txt". Is it necessary that the Tag directories be inside the Homer directory? And, I have created the tag directories using the SAM alignment format. Is it required to convert to BAM for homer to read?

Thanks in advance!
