Scoring function and qualities analyzed for the LT-Score.

The scoring function for the calculation of the LT-Score is a sum: to score a service, the qualities listed in the table are evaluated; all scores sum up to a maximum of 41 points for services; for collections of several services only the qualities one through seven are evaluated and summed up to a maximum of twelve points.aRegular usability results in two points, exceptional usability is awarded with three points. One point is given to services with low usability, and zero if the service was unavailable.bIf the registration is limited to an email address for reporting results, one point is awarded.cFor a fair testing possibility, we require either easily obtainable example data or only standard file types such as FASTA, PDB, GFF, etc. for the input. See Methods for more information. Two points were awarded if we were unable to determine whether we had a fair testing possibility or not.dIf we were unable to determine functionality due to a lacking fair testing possibility, four points were awarded, while clearly non-functional services received zero points.
