Computational Methods and Tools; Statistical Software and The paper emphasizes graphical possibilities and does not These explanations differ from common statistical analysis in that they Model-Based Clustering for Gene Expression Data. Microarray images were imported into BlueFuse v. Using BASE, the raw intensity readings from each microarray were subjected to cross-channel correction in order to correct for cross-talk between the fluorophores [ 34 ], and the LOWESS method [ 35 ] was used to perform within-array normalization of intensity values. For sequencing library synthesis, polyadenylated RNAs were purified using oligo dT-beads Invitrogen with random hexamers, then used as primers for the cDNA library construction prior to paired-end sequencing.

RNA-seq reads were subjected to quality control using the standard Illumina pipeline. Raw sequence reads were mapped against the reference genome the GRCh37 assembly from E nsembl [ 20 ] using the following command to T op H at 2 [ 21 ]: --bowtie1 -p 8 -r 20 --solexa-quals --coverage-search --microexon-search --library-type fr-unstranded. No trimming of reads was performed prior to mapping. The feature probe generator function in S eq M onk was used to generate probes based on mRNA annotations from E nsembl. The number of reads that mapped to each probe was then quantitated, and normalized using the widely used RPKM method [ 22 — 29 ].

A detailed list of the parameter values selected for data importation, probe generation, and read count normalization and quantitation is available in the electronic supplementary material, table S7. The method used to select probes that correspond to those on the microarrays is given in a following section.

Correlations between variables were determined in three different ways: Pearson correlation between untransformed values, Pearson correlation between log-transformed values i. The statistical significance of differences between correlations was calculated by applying Fisher's z -transformation to the correlation coefficients. Log-transformation of variables was done after other transformations i.
The consistency among the four microarrays was evaluated by comparing both normalized intensity values and FC values among pairs of microarrays. All microarray probes were used, not just those for which a corresponding RNA-seq probe was identified. The reproducibility of the RNA-seq data was evaluated by comparing both normalized read counts and FC values.
All RNA-seq probes were used, not just those for which a corresponding microarray probe was identified. In order to determine the correspondence between the real probes on the DNA microarrays and the virtual probes generated by S eq M onk , two different methods were used: a method based on probe sequences and a method based on E nsembl transcript IDs.
The sequence-based mapping method was performed as follows. Associated with each microarray probe M i was the sequence M S i of that probe, as well as the chromosome M C i on which that sequence is found. The record associated with each probe R j generated by S eq M onk contained the chromosome R C j on which that probe is found, as well as the start and end position of the probe on that chromosome.
Let R S j denote the sequence bounded by those chromosome locations. If there did exist such a probe, then M i was considered to correspond to R j. If there did not exist a probe R j for which M S i was a subsequence of R S j , then a second mapping method was attempted based on E nsembl transcript IDs. Some microarray probes had exactly one associated E nsembl ID; others had more than one or none at all. If there was, then M i was considered to correspond to R j and no further elements of M E i were examined.
In many cases, a given microarray probe mapped to more than one RNA-seq probe typically representing splice variants of the same gene based on sequence. If not, then one of the identified RNA-seq probes was arbitrarily selected to correspond to that microarray probe.

If no mapping could be found for a given microarray probe via either sequence or E nsembl IDs, then it was not included in the comparison between the microarray data and the RNA-seq data. Prior to comparing the RNA-seq data and the microarray data, the reads from the two RNA-seq replicates for each cell state were combined, giving a single read count for PRO and a single read count for QUI for each probe. These combined data were then compared to each individual DNA microarray. All comparisons were performed using only microarray probes for which a corresponding RNA-seq probe was found and vice versa.
The RNA-seq data were compared to the microarray data in three ways. Let S represent the set of all probes for which a correspondence was found between the microarray data and the RNA-seq data. The number of probes n that were in both lists was then ascertained.
In each trial, k probes were randomly selected without replacement from S. The selected probes were then placed back into S , and k additional probes were selected without replacement. The number of probes p found in both lists was recorded. Each of these genes had a corresponding probe in both the RNA-seq data and the microarray data. Some genes were selected arbitrarily, while others were selected because they were upregulated in either the RNA-seq data, the microarray data or both. The average FC value among the four normalizing genes was used for comparing to the RNA-seq data and microarray data.
If there were multiple microarray probes for a given gene, then the geometric mean of the FC values of those probes was used. The data used for this study have been deposited in Gene Expression Omnibus [ 3 ] under the accession nos. The authors have no competing interests. Login to your account. Forgot password?
