Hi organizers, We have been facing proteinID maching problem in PGX sub2 breast challenge. There is no error in express lane but final submission is with following error: "predictions.tsv: All proteinID in the goldstandard must also be in your file. You are missing: TGM1,DAPL1,RAPGEF3,HKDC1,TKTL1,SYS1,UPK1B,SUSD5,ZFP62,NPR1,AQP5,NGEF,SLC38A2,ENPP6,CRB2,TSPAN3,KLK8,ATP2B2,PTTG1IP,ADCY7,FAT2,CDS1,KDELR1,ALG8,ALG3,PNMA3,PAGE2,PKHD1L1,DPEP3,SLC9A6,CYP11A1,SOX17,DERL2,SLC35A3,CLDN1,CLDN4,CLDN6,PAX8,PLSCR4,GZMK,SLC35B1,ELOVL1,PCDH19,FLG,XAGE2,EPHA2,PLP2,CADPS,APH1A,MECOM,NECTIN3,ND4,PLPP1,PLPP2,KLHL14,RABL2A,CALB1,RGL3,ALG10,FADS3,FAM171A1,GLB1L2,EMILIN3,FAM20A,LRRC32,ATP1A2,COL21A1,TMEM231,SIGMAR1,PINX1,SEL1L3,ITM2C,UPK3B,CYTB,CCDC167,CYP2U1,PRUNE2,OGDHL,CBWD1,CALHM2,MFSD1,OVGP1,TMEM160,PCDHB8,PXMP2,TPSAB1,ST6GALNAC1,NRM,EBP,MUL1,SDHD" None of the above id is present in the "prospective_breast_pro_gold_express.txt" present as syn11378102 (https://www.synapse.org/#!Synapse:syn8564279) which has been uploaded on 14 Nov itself. Please advice. Its taking a lot of time and effort to debug where we have reasons to believe that testing files are not compatible with the gold standard given under training set folder. Thank you.
