Should the csv pointing to chunks be updated as well?

        // Chunks
        exportCsv(
            VCF_CHUNK_GLIMPSE.out.chunks.map{ meta, file ->
                [meta, [2:"prep_panel/chunks"], file]
            },
            ["id", "chr"], "panel,chr,file",
            "chunks.csv", "prep_panel/csv"
        )
    }
    ```

        )
    }
    ```

It is already updated to

// Chunks
exportCsv(
    VCF_CHUNK_GLIMPSE.out.chunks.map{ meta, file ->
        [meta, [2:"prep_panel/chunks/glimpse1"], file]
    },
    ["id", "chr"], "panel,chr,file",
    "chunks_glimpse1.csv", "prep_panel/csv"
)
