cleavable crosslinker configuration crash 1.7.6.7

[grandrea]

Somehow, adding the lines

custom:loss:CleavableCrosslinkerPeptide:MASS:0;NAME:C
loss:CleavableCrosslinkerPeptide:MASS:82.04186;NAME:S;aminoacids:K,nterm,S,T,Y

to configure my crosslinker as cleavable crashes my search with the error

this happens with and without the "custom" in front... i can't find out where the error is. Any clues?

Thanks!

looks like that java somehow does see all the class files. I assume you use a fairly recent version of xiSEARCH? You could try to unzip the jar file (is basicylly just a zip file) and see if the class file is there rappsilber/ms/sequence/ions/loss/CleavableCrosslinkerPeptide.class

indeed this was solved by re-downloading the software. I don't know what corrupted the .jar file i had
