Depth Coverage on Unlocalized Scaffolds

Question

[harper.fauni]

Hi,

Is there a way to find the read depth for gl contigs (unlocalized and unplaced sequences) using samtools(or any tool) and a bam file?

If the read depth for gl contigs can't be obtained from using any tools, should these gl contigs that have gene names be manually looked at through IGV (Integrative Genomics Viewer) using the bam file?

Thanks and have a nice day!
