Problem of New DESeq without any replicates

[anyone1985]

Recently, I do some RNA-seq analysis. The old version of DESeq do well with the data set without any replicate. However, I came across some error when i ran the newest version following the userguide. Please help.

> cds

assayData: 49 features, 2 samples

> cds=estimateDispersions(cds, methold="blind", sharingMode='fit-only')

should be

> cds=estimateDispersions(cds, method="blind", sharingMode='fit-only')

Also try including the fitType setting:

> cds=estimateDispersions(cds, method="blind", sharingMode='fit-only',fitType="local")
