XCMS Online / Re: Problem uploading files
I have tried uploading to the dataset uploading area as well without much luck. However, I was able to upload data using internet explorer in both the stored data tab and in the create job area. Another problem arose though in all three browsers that I tried (chrome, firefox, and internet explorer) where I could not change job parameter settings. They were all grayed out.

XCMS / Heat Map Visualization
I have been attempting to visualize the data as a heat map but haven't found much luck in doing so. Ideally, I'd love to display the data showing changes in abundance with color between two conditions compared to a control group. Does anyone know the correct R code to perform this action? I have looked for the code to make a heat map but I really need something more similar to how microarray data is displayed.
Thank you for your input and if you require further information, please do not hesitate to ask,

XCMS Online / Analytical versus Biological Replicates
I have a statistical question. I have three biological replicates and for each biological replicates two injections (2 analytical replicates). When performing an analysis, I see no way to differentiate between the two types of data sets. I have concerns that with an n of 6 compared to 3, some intensities may be made more significant than they are. However, I clearly want to control for machine produced error. Does anyone have any suggestions for dealing with this problem?
Thank you,
