# BCL Convert software output files

BCL-convert was initially included in the DRAGEN Suite and greatly reduces the overall time needed to convert BCL files to FASTQ files with the FPGA hardware acceleration. Starting 28-JUL-2020, BCL convert has been released as a [stand-alone software](https://emea.support.illumina.com/sequencing/sequencing_software/bcl-convert/downloads.html) and has parity to the BCL convert included with DRAGEN 3.6.3 and above version

#### **Output files**

The following files are created in the /Reports/. Detailed Information can be found in the [bcl convert user guide](https://support.illumina.com/downloads/bcl-convert-user-guide.html).

![](/files/sjdpsCYP3irrz0WaKafB)

Columns (if applicable) of the files included below.

* **Adapter\_Metrics.csv**
  * ![](/files/vaMIJSHh1N2uBOkkJAxG)
* **Demultiplex\_Stats.csv**
  \*

  ```
  ![](/files/WF5TLjPiF4peSZIKj3C5)
  ```
* **fastq\_list.csv**
  * This file that can be used for DRAGEN analysis and contains the file path and information to input a single Sample for downstream analysis. (Note: using a single FASTQ file list will not batch launch all samples present. Rather, if `--fastq-list-all-samples true` is used, it will merge all sample information into a single dataset.)
  * RGID
  * RGSM
  * Lane
  * Read1File
  * Read2File
* **Index\_Hopping\_Counts.csv**
  * \*Only applicable when Unique Dual Indexes (UDIs) are used, otherwise the file will output a header-only file\
    ![](/files/W4t8Z1A0uexi8jZEgnFg)
* **IndexMetricsOut.bin**
  * Binary file to be used with SAV
* **RunInfo.xml**
* **SampleSheet.csv**
* **Top\_Unknown\_Barcodes.csv**
  \*
