Hi to all,
I was playing with samr, and I found out that when I try to apply it to
some data with no variance, it always return the error message:
*"invalid number of intervals"*
example of the one dataset:
gene_name gene_index 1 1
1 1 -0.719512126 -0.719512126
2 2 -1.2910361 -1.2910361
3 3 -2.503576664 -2.503576664
4 4 -2.595720177 -2.595720177
5 5 0.337146509 0.337146509
6 6 -0.336816551 -0.336816551
7 7 0.463494332 0.463494332
8 8 -0.143871617 -0.143871617
9 9 -0.75348224 -0.75348224

Does any one know if the origin of the problem is the absence of variance?
Thanks in advance
