PSDI will be operating at risk during the period 30th March - 7th April due to system maintenance and holiday closures. During this time our helpdesk will be unavailable and some services may become temporarily unavailable. We apologise for any inconvenience this may cause.

Depositors are expected to comply with the PSDI Community Data Collections Policy. 

Depositors are required to accept and comply with the TEM-ParticlesDB deposit conditions. 

File formats for experimental data are dm3, dm4, TIFF 

File formats for synthetic data are png 

File formats for segmented data are png 

File formats for meta data are csv, db 

Please add the resolution (pixel size) to which the images were obtained in the “Pixel size” custom domain metadata field only if this is constant to all the files. Otherwise, either upload the dm3 files with the information, or a csv with filename + pixel size + pixel unit

Acceptance into the community is determined by the TEM-ParticlesDB Community Administrators 

Descriptive metadata to accepted standards for discovery and description, must be assigned to each dataset. 

A Creative Commons CC0 licence is the default licence for deposits, however depositors are expected to pay careful consideration to this and must always ensure that an appropriate licence is selected. 

There is an option to set an embargo period for datasets. 

There are no charges to individual researchers for deposit or storage of datasets. 

Before publication in TEM-ParticlesDB, datasets and metadata will be reviewed for accuracy by TEM-ParticlesDB appointed reviewers. The deposit will also be inspected to ensure it is within the scientific scope of TEM imaging of nanoparticles as outlined above. 

Datasets should be no larger than 100GB.
