Why Can't I access my mounted directory in centOS?

Hi everyone, I’m extremely new to Docker and CentOS and I’ve built an image upon a Dockerfile called tools. I’ve installed the bcftools repositories to view and annotate vcf and bcf files.

From command line, I run a new container in the image and mounted a directory to be accessed in the container, a folder DFiles on my desktop, with docker run -it -v /Users/BralK/Desktop/DFiles tools

But when I try to view a file, I can’t. It gives me [E::hts_open_format] Failed to open file OCT1.genome_min.vcf Failed to open OCT1.genome_min.vcf: No such file or directory
Obviously I’m not accessing this folder properly. Can anyone help me figure out how to successfully view my files? I’ve tried it with many other files and get the same response.

Please let me know if you need any more information.

Thanks so much.
