Hi everyone: I tried to run following codes to compute Semantic Similarity Matrix (SSM) using different measure, combine, database and category to find the best estimate,but in some cases I got an error as follow. I some cases I didn't get the error. here is an example that I got the error:

meshdata <- meshdata(MeSHDb="MeSH.Osa.eg.db", category="D", computeIC=T, database="gene2pubmed")

SSM_rice=geneSim(geneID1=geneID1, geneID2 = geneID2, measure =   "Resnik", combine = "BMA",semData=meshdata)

Error in infoContentMethod_cpp(ID1, ID2, .anc, IC, method, ont) : 
  Expecting a string vector: [type=NULL; required=STRSXP].
In addition: Warning message:
  In `[.data.frame`(meshtbl, meshtbl$meshID %in% id, "parent") :
  restarting interrupted promise evaluation

in addition when I reduced the number of the gene to 10 and 20 for geneID1 and geneID1, respectively, the problem solved, but I need to use all genes. See the following codes:

geneID1=geneID1[1:10]
geneID2=geneID2[1:20]
SSM_rice=geneSim(geneID1=geneID1, geneID2 = geneID2, measure =   "Resnik", combine = "BMA",semData=meshdata)
SSM_rice[1:6,1:6]

I'm using R version 3.4.3 (2017-11-30), ‘meshes’ version 1.4.0 and Bioconductor 3.6.

Thanks in advance!
