Normally, once a dataset is made public, it is locked and our policies do not allow users making any further changes or removing it from the public domain. It is similar to publishing a manuscript; once it is published, you cannot take it back. However, our policy also state that: Experiments may be deleted in FlowRepository at the discretion of FlowRepository administrators if experimental data are found to be fabricated, fraudulent, infringing of the rights of others, submitted without the permission of the rightful owner, or other good cause. Based on this, our administrators may be able to change your experiment back to private if there is a good reason to do so. Please contact us with specific details and explanation what happened and what you intentions are, and we will do our best to assist you.
