Conclusion
12
➢Clear and complete documentation of the experiment is
a prerequisite of valuable results
➢Systematic and safe storage of data and metadata is
the basis of preserving know-how and state of the art
➢Transparent documentation and publication of
metadata increases the plausibility of the results,
scientific communication and prevents data misuse or
manipulation
➢eLabFTW applied for SEM facility
