However, when HeLa cells were grown in a 3D matrix (data not shown), or as a xenograft tumor, MMP-10 expression was induced.
The two-color images taken as an input to CICA are coupled in a matrix termed data matrix.
If we think of the data in a matrix format, the data set for each network (Fig. 1) consists of a matrix with 100 rows and 100 columns.
Clicking on the "load" button, the matrix data file name (such as the "colon&ovarian&pancreatic&breast.matrix" provided by the hSAGEing tool as the built-in example file) and SAGE libraries (listed in the pull-down window for libraries A and B) appear in the "matrix data" and "condition setting" fields, respectively (Figures 2A and 2B).
A classical use of feature selection analysis [ 2] is to identify the most discriminating features or dimension in a matrix of microarray data [ 3].
The basic idea is that we place our measured data in a data matrix (marked X), in which the rows correspond to the samples (in this case, coins), whilst the columns represent the studied properties (here: metal concentrations).
Traditional classification algorithms from data mining domain, however, require the input of training data to be formatted in a data matrix where the columns represent features/attributes that characterize the voice data, and the rows are the instances of the voice data.
A concatenation of SNPs were gathered in a data matrix (95% majority SNP matrix) using the program kSNP v. 2 ([ Gardner and Slezak 2010] http://sourceforge.net/projects/ksnp, last accessed June 3 , 2013.
This block transforms the data vector d in a data matrix D ( O ) ∈ A N o × K ~ N o, mapping the m th element of d to D ( O ) m - N o ⌊ m N o ⌋, ⌊ m N o ⌋ + 1.
Usually, gene expression data is arranged in a data matrix, where rows represent genes and columns represent conditions.
