I am trying to forge a genome from the microtus ochrogaster genome, with this command

forgeBSgenomeDataPkg("/mnt/Prairie_Vole_Data/Arjen_Folder/Arjen/genomefiles_mo/NCBI/BSgenome.Mochrogaster.NCBI.micOch1.0-seed")

but keep getting errors, either this one:

Error in .make_Seqinfo_from_genome(genome) : 
  "MicOch1.0" is not a registered NCBI assembly or UCSC genome (use registered_NCBI_assemblies() or registered_UCSC_genomes() to list the
  NCBI or UCSC assemblies/genomes currently registered in the GenomeInfoDb package)
In addition: Warning messages:
1: In forgeBSgenomeDataPkg(y, seqs_srcdir = seqs_srcdir, destdir = destdir,  :
  field 'provider_version' is deprecated in favor of 'genome'
2: In forgeBSgenomeDataPkg(y, seqs_srcdir = seqs_srcdir, destdir = destdir,  :
  field 'release_name' is deprecated

Or this one:

Error in h(simpleError(msg, call)) : 
  error in evaluating the argument 'expr' in selecting a method for function 'eval': <text>:1:3055: unexpected input
1: W_004949236.1","NW_004949237.1","NW_004949238.1","NW_004949239.1","NW_004949240.1","NW_004949241.1","NW_004949242.1","NW_004949243.1","NW_004949244.1","NW_004949245.1","NW_004949246.1","NW_004

In addition: Warning messages:
1: In forgeBSgenomeDataPkg(y, seqs_srcdir = seqs_srcdir, destdir = destdir,  :
  field 'provider_version' is deprecated in favor of 'genome'
2: In forgeBSgenomeDataPkg(y, seqs_srcdir = seqs_srcdir, destdir = destdir,  :
  field 'release_name' is deprecated

The second error I can fix by simply removing the seqnames field from the seedfile, but then I get the first error.

Here is my seed file:

You should take a look at the BSgenomeForge vignette. In particular 2.2.4, the 'other fields', under which it explains that you only need the seqnames entry if you are supplying bare sequence (fasta) sequences. Which you are not (you are supplying a .2bit file).

Probably the most relevant example you could use is the first one, for ferret:

But do note that provider_version should now be 'genome', 'release_name' has been deprecated.

Anyway, I always find it easier to get an example file, a listing of which you can get by doing

dir(paste0(path.package("BSgenome"), "/extdata/GentlemanLab"))

Also NCBI typically provides FASTA files with ugly sequence names (e.g. GenBank or RefSeq accessions) so forging a BSgenome data package for an NCBI assembly typically requires a preliminary step. This step takes the NCBI FASTA file (GCA or GCF) and turns it into a clean 2bit file. For the GCA_000317375.1 assembly (MicOch1.0), this can be done with:

### Download GCA_000317375.1_MicOch1.0_genomic.fna.gz from
### https://ftp.ncbi.nlm.nih.gov/genomes/all/GCA/000/317/375/GCA_000317375.1_MicOch1.0/

library(Biostrings)   
dna <- readDNAStringSet("GCA_000317375.1_MicOch1.0_genomic.fna.gz")

### Check the seqnames.
current_GenBankAccn <- unlist(heads(strsplit(names(dna), " ", fixed=TRUE), n=1L))
library(GenomeInfoDb)
chrominfo <- getChromInfoFromNCBI("GCA_000317375.1")
expected_GenBankAccn <- chrominfo[ , "GenBankAccn"]
stopifnot(setequal(expected_GenBankAccn, current_GenBankAccn))

### Reorder the sequences.
dna <- dna[match(expected_GenBankAccn, current_GenBankAccn)]

### Rename the sequences.
names(dna) <- chrominfo[ , "SequenceName"]

### Export as 2bit.
library(rtracklayer)
export.2bit(dna, "MicOch1.0.sorted.2bit")

Then use the following seed file (copied from BSgenome.Amellifera.NCBI.AmelHAv3.1-seed located in the BSgenome package, and edited for MicOch1.0):

FWIW I used the above file to forge my own BSgenome.Mochrogaster.NCBI.MicOch1.0 package:
