**Field descriptions**
1. **DOI**
DOI of the original publication where the experimental data originates.
2. **TEMPERATURE**
Temperature of the experiment.
3. **MOLAR_FRACTIONS**
Dictionary of molar fractions of bilayer components. For example:
```
MOLAR_FRACTIONS:
POPC: 0.93
CHOL: 0.07
```
4. **ION_CONCENTRATIONS**
Dictionary of ion concentrations of the system ([ion]= Nion*[water]/Nwater, where [water] = 55.5 M). For example:
```
ION_CONCENTRATIONS:
POT: 0
SOD: 0.1
CLA: 0.1
CAL: 0
```
5. **TOTAL_LIPID_CONCENTRATION**
Total concentration of lipid components ([lipid]= Nlipid*[water]/Nwater, where [water] = 55.5 M). If exact concentration is not known, but experiments are performed in excess water, ’full hydration’ can be given.
6. **COUNTER_IONS**
Type of counter ions if present.
