+**Disclaimer!**  
+This data format is targeted for a single use case and should not be
+used for general data registration purposes. Please use the
+[NGS single-end / paired-end data](#ngs-single-end--paired-end-data)
+format for now.
+
+**Responsible dropbox:**
+[QBiC-register-imgag-dropbox](drop-boxes/register-imgag-dropbox)
+
+**Resulting data model in openBIS**  
+Q_TEST_SAMPLE -> Q_NGS_SINGLE_SAMPLE_RUN (with sample code) -> DataSet
+of type Q_NGS_RAW_DATA (directory with raw sequencing files contained)
+
+Example sample ids:
+
+QABCD001AE (Analyte, Q_TEST_SAMPLE)  
+NGS[0-9]{2}QABCS001AE (Sequencing Result, Q_NGS_SINGLE_SAMPLE_RUN) where
+the running two-digit number is taken from the identifier suffix from
+the `genetics_id` in the metadata file.
+
+**Description**  
+For paired-end sequencing reads in FASTQ format, the file structure
+needs to look like this
+
+```
+<QBIC sample code> // Directory
+    |-- file1.fastq.gz
+    |-- file2.fastq.gz
+    |-- metadata
+    |- ...
+```
+
+**Expected metadata**  
+Additional metadata is required in this format case and expected to be
+noted in JSON in a file called `metadata` and following the
+[upload metadata schema](drop-boxes/register-imgag-dropbox/upload-metadata.schema.json).
+A valid JSON object can look like this:
+
+```
+{
+    "files": [
+        "reads.1.fastq.gz",
+        "reads.2.fastq.gz"

-## Expected data structure
-The data structure needs to be a root folder, containing a file `metadata` following the [upload metadata schema](upload-metadata.schema.json). In addition, the folder shall contain files of type `fastq/fastq.gz` and/or `vcf/vcf.gz` and/or `GSvar/GSvar.gz`.

-## Expected metadata
-Metadata is expected to be noted in JSON and following the [upload metadata schema](upload-metadata.schema.json). An example JSON entry can look like this:
-
-```
-{
-    "files": [
-        "reads.1.fastq.gz",
-        "reads.2.fastq.gz"

-        "processing_system": "Test system",
-        "tumor": "no"
-    }
-}
-```
-
-The sample code for `id_qbic` can be of type `Q_TEST_SAMPLE` or `Q_BIOLOGICAL_SAMPLE`. In the latter case, a new sample of type `Q_TEST_SAMPLE` is created and attached as child to the biological sample. The data-set will be registered under this test sample then.
