Sometimes, PREDetector detects that the genome annotation is not good enough to allow the program to display the prediction results. When such case is detected, a warning is displayed and the genome cannot be downloaded. You could contact the Hedera-22 team ( to improve the annotation of your genome of interest in order to make regulon predictions feasible.
Users that will subscribe to 'PREDetector Unlimited' will have access to a series of options that require storage space such as i) the number of genome sequences downloaded, ii) the number of position weight matrices in their private repository, and iii) conservation of all prediction jobs performed. Subscribing to the 'Unlimited PREDetector' version is considered as a support of users for the further development of the PREDetector software and therefore subscribing users will benefit from services of the team at identifying and solving specific problems. Finally, users that subscribed to 'PREDetector Unlimited' will benefit of important discounts to 'extra' services that would be asked to the PREDetector team such as genome assembly, genome annotation, prediction jobs on your own genomes or genomes unavailable from public repositories, ...

In principle, the Hedera-22 team should be able to propose a solution and/or any service associated with genomic investigations. For specific demands please contact the team at
