petal specifications


Unique identifier OMICS_12597
Name petal
Software type Package/Module
Interface Command line interface
Restrictions to use None
Input data The user supplies the expression data file to petal. In addition, there are four optional steps: the selection of an association measure, user-specified thresholds (for the advanced user), the upload of a list of genes which are of particular interest to the researcher, and a gene annotation file. Additionally, the user has the option to evaluate their data distribution by using the function graphHistQQFromFile before constructing a network model.
Output data Upon completion, petal’s accessible files include: general information file (.txt), network file (.txt), adjacency matrices (.RData), two topology tables (.txt), vicinity network files (.txt), and the expression profiles (.tiff) of each vicinity network. The network file can be directly uploaded into Cytoscape.

Discovering Condition Specific Gene Co Expression Patterns Using Gaussian Mixture Models: A Cancer Case Study

Sci Rep
PMCID: 5561081
PMID: 28819158
DOI: 10.1038/s41598-017-09094-4

[…] n modules”. A variety of software tools exists for GCN construction with each employing different approaches for identifying co-expression. These include tools such as, WGCNA, CLR, MRNET, RMTGeneNet, petal and FastGCN. WGCNA is the most popular network construction tool in terms of citations.Some studies use hundreds to thousands of samples to create a GCN–. The use of hundreds of samples for GCN […]


The common transcriptional subnetworks of the grape berry skin in the late stages of ripening

BMC Plant Biol
PMCID: 5450095
PMID: 28558655
DOI: 10.1186/s12870-017-1043-1

[…] CNA (Weighted Gene Co-expression Network Analysis) is one approach that was effectively used to identify highly connected hubs in gene subnetworks for Arabidopsis [, ] and Vitis []. Another approach, petal [], was developed recently to provide a truly scale-free and small-world network model for large-scale Omics analyses. A common set of transcriptional changes occurring in the late ripening stag […]


Comparative transcriptomics of mountain pine beetle pheromone biosynthetic tissues and functional analysis of CYP6DE3

BMC Genomics
PMCID: 5397757
PMID: 28427347
DOI: 10.1186/s12864-017-3696-4

[…] ertheless, mevalonate pathway enzymes are more predominantly represented in fed males compared to females, consistent with frontalin production (Fig. ). In parallel, co-expression network analysis by petal using a Spearman Correlation Coefficient and similarity threshold of 0.808 also isolated candidate genes. As these expression data were not normally distributed, the Spearman Correlation Coeffic […]


The tomato floral homeotic protein FBP1 like gene, SlGLO1, plays key roles in petal and stamen development

Sci Rep
PMCID: 4740859
PMID: 26842499
DOI: 10.1038/srep20454

[…] organs in tomato showed that the SlGLO1 mRNA was highly accumulated in petals and stamens (), which was coincidence with the study of Geuten and Irish where they show SlGLO1 is expressed in incipient petal and stamen primordia in early developmental stages by in situ hybridization. These results indicate that SlGLO1 may have a specialized function in flower development process. […]
