what is the proper way to save the distance matrix?

[Jingpeng Wu]

Dear Greg, 

I tried to save the distance matrix with csv format, but the output have some extra columns. I can just ignore them?

here is my code to reproduce:

```{r}

library(nat)

library(nat.nblast)

# plot some test data (?kcs20 for details)

# Drosophila Kenyon cells processed from raw data at http://flycircuit.tw

head(kcs20)

mydotprops = dotprops(kcs20)

aba=nblast_allbyall(mydotprops)

hc=nhclust(scoremat=aba)

plot(hc)

write.csv2(aba, "aba.csv")

```

Thanks,

Jingpeng

I would suggest write.csv and use the row.names=F argument. See ?write.csv help.
