Dear list, Hi! I have a question about EBarrays. It seems to me that EBarrays requires the array data not be transformed. The data called 'gould' has been used as an example in the vignette. And by looking at first few data it could support my guess. > gould[1:4,1:4] CopK759 WFK759 WFK842.12 CopN9CK758.1 S80456.s.at 336.691 281.002 360.969 258.360 S82229.s.at 1461.250 1312.740 857.921 1559.740 U01022.s.at 1057.500 668.640 879.656 885.964 U02553cds.s.at 896.886 1207.350 1302.750 1302.970 Am I correct?

Hi, Allen. Your best bet is to read all the documentation thoroughly. For example, look at the second sentence of section 2 of the vignette from which you are taking your example. It suggests that your guess is incorrect. Sean
