+# Pheno006 example dataset: Two sessions with one imaging-only session. No sessions files
+
+This dataset contains imaging and phenotypic data from the baseline session and phenotypic data from followup sessions. This an example of a case where adding sessions files does not provide any new information. In other words, a sessions file is not strictly necessary here. The file tree is as follows:
+
+```bash
+pheno006
+|-- README.md
+|-- participants.json
+|-- participants.tsv
+|-- phenotype
+|   |-- ace.json
+|   `-- ace.tsv
+|-- sub-01
+|   `-- ses-baseline
+|       `-- anat
+|           |-- sub-01_ses-baseline_T1w.json
