why this error appears "all scheduled cores encountered errors in user code" is it related to core processor of servers?

Question

We are analyzing sequencing data while filtering and trimming fastq files encountered following error. Is the following error due to unavailability of core for processing commands?

Error in colnames<-(*tmp*, value = c("cs103_R1_dada.fastq", "cs110_R1_dada.fastq", : attempt to set 'colnames' on an object with less than two dimensions In addition: Warning message: In mclapply(seq_len(n), do_one, mc.preschedule = mc.preschedule, : all scheduled cores encountered errors in user code >

Answer 1

As pengchy suggested there may be something wrong with function. try the same call by using lapply and error message will be more informative.
