Yes, Nanopore reads are ideal for the detection of structural variation, and there are a number of ONT workflows and third-party tools available for this process.
Structural variants (also known as SVs) are typically identified after the alignment of reads against a reference sequence. The resulting aligned read data (typically in BAM format) are used as input and a variant call format (VCF) file is generated containing variant predictions against this reference sequence.
For third-party tools, please see their GitHub pages for installation and usage. To address any issues with these and other third-party tools, please post to the Issues tab on the individual GitHub repositories as we cannot offer support for third-party software.
