Error Message: Cannot separate the identifier from the value for attribute

[luisafmc]

Hi,
I'm trying to build an index with the annotation file and fasta file of the most recent from of mouse reference genome. I've donwloaded from NCBI ftg (https://ftp.ncbi.nlm.nih.gov/genomes/all/GCF/000/001/635/GCF_000001635.27_GRCm39/GCF_000001635.27_GRCm39_genomic.fna.gz and https://ftp.ncbi.nlm.nih.gov/genomes/all/GCF/000/001/635/GCF_000001635.27_GRCm39/GCF_000001635.27_GRCm39_genomic.gtf.gz)

This is my code:
RSEM/software/RSEM-1.2.25/rsem-prepare-reference --gtf ~/Data/M_musculus/GCF_000001635.27_GRCm39_genomic.gtf --bowtie2 --bowtie2-path RSEM/software/bowtie2-2.2.6 ~/Data/M_musculus/GCF_000001635.26_GRCm38.p6_genomic.fna ~/RNA_Analysis/02_Mapping/mouse_ref

But I'm having this error:
rsem-extract-reference-transcripts /home/luisafmc/RNA_Analysis/02_Mapping/mouse_ref 0 /home/luisafmc/Data/M_musculus/GCF_000001635.27_GRCm39_genomic.gtf 0 /home/luisafmc/Data/M_musculus/GCF_000001635.26_GRCm38.p6_genomic.fna

Plase check if you provide correct parameters/options for the pipeline!

Could you help me?
