[BioC] Error while running DESeq

[nisha [guest]]

While running DEseq for DGE, I am facing following problem.

Error in preplot.locfit.raw(object, newdata, where, what, band) :
  NA/NaN/Inf in foreign function call (arg 2)
Calls: estimateDispersions ... predict.locfit -> preplot.locfit -> preplot.locfit.raw -> .C
In addition: Warning messages:
1: In lfproc(x, y, weights = weights, cens = cens, base = base, geth = geth,  :
  compparcomp: perfect fit
2: In lfproc(x, y, weights = weights, cens = cens, base = base, geth = geth,  :
  procv: parameters out of bounds
3: In lfproc(x, y, weights = weights, cens = cens, base = base, geth = geth,  :
  max_nr not converged
Execution halted

My file does not contain any "NA or empty cells", I have tried every possible thing but still not able to find the problem behind this error. Kindly suggest me some solution for this. Waiting for your positive response.
