Ah, and the sort. My find(1) finds files quite out of order, maybe because of ext4?

$ find dnn4_pretrain-dbn_dnn_denlats/lat1 -name '*.gz' | head -3
dnn4_pretrain-dbn_dnn_denlats/lat1/41/BertrandPiccard_2009G-0097823-0098802.gz
dnn4_pretrain-dbn_dnn_denlats/lat1/41/BernieKrause_2013G-0047540-0048091.gz
dnn4_pretrain-dbn_dnn_denlats/lat1/41/BethNoveck_2012G-0024724-0026655.gz

I do not know if sorted promise is used on the lat.scp later, so I sorted it just in case. May not be really required.
