[Category:SPheno](/Category:SPheno "wikilink") There are many options which can be used in the block `SPhenoInput` in the Les Houches input file to set up the calculations and the output done by SPheno :

 `76` if `1`, input files for HiggsBoundsand `HiggsSignals`are written; default is `1`



 `77` if `1`, output is written to be used with MicrOmegas: running masses for light quarks are written instead of pole masses (necessary for the direct detection calculation) and real rotation matrices for Majorana fermions are used; default is `0`



 `86` sets the maximal width which is taken as ’invisible’ in the output for HiggsBoundsand `HiggsSignals`; default is `0.`



 `88` sets a maximal mass of particles which are included in loop calculations; default is 10<sup>16</sup> GeV. Note, this option must be turned in SARAHfirst
