I am not very familiar with R and get error massages like this:
"Batch submitting query [==================================>------------------] 67% eta: 3sError in getBM(filters = "ensemblgeneid", attributes = c("ensemblgeneid", : The query to the BioMart webservice returned an invalid result: biomaRt expected a character string of length 1. Please report this on the support site at http://support.bioconductor.org"
They are all the same but differ in progress [%] and time [s]. A few days before everything was working but today I get this error but did not changed the script, the raw data or updated anything.
What might be a problem?
