log4j: WARN Please initialize the log4j system properly
I am running GATK CNV, and got the following error:
log4j: WARN No appenders could be found for logger (org.broadinstitute.hdf5.HDF5library).
log4j: WARN Please initialize the log4j system properly.
log4j: WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
I hope that the above WARNING did not affect my GATK run and the resutls.
Can someone please also tell me know to exactly fix the above the WARNING. i could not find the answer from http://logging.apache.org/log4j/1.2/faq.html#noconfig.
Thank you very much & best regards,
