I was wondering if it does exist a similar tool, but free... I' trying to reproduce some results I found on a recent paper, and I would rather prefer to try with a different tool. Otherwise, I think I'll go with the 2 free weeks that they offer...
The thing is that all those commercial pathway providers like Ingenuity and GeneGO offer a lot of content that they developed in house for specific fields. Ingenuity is quite good in the cardiovascular field and GeneGo's Metacore is good Toxicology for instance (and more metabolite directed research in general). So if you did something specifically in Ingenuity or want to reproduce that you might not easily find an alternative. Although all the content they offer is based on knowledge freely available in other pathway databases (Ingenuity started with a lot of KEGG pathways) and the literature.
That being said there are a lot of freely available pathway analysis tools and pathways. Check out Pathwaycommons for a kind of integrated approach (that includes Reactome a.o). You might also want to try our own WikiPathways and the accompanying pathway analysis tool PathVisio. At the PathVisio download page we also offer converted KEGG pathways for many species that you could also analyze using PathVisio.
Have you tried Reactome pathway analysis tool?
Maybe some kinds of analysis done with Ingenuity can be done with this tool. if you're working with human proteins maybe you find it useful

QuaternaryProd is an open-source alternative to IPA. It is an R package which can be used to predict upstream regulators given gene expression data. The R package uses StringDB and the "Quaternary Statistic" for performing causal inference.
The R package can be downloaded from Bioconductor (link) and the latest version is on github (link)
The original paper can be found here.
You could also try GeneMANIA: http://www.genemania.org
We include everything in Pathway Commons, plus genetic interactions, co-expression relationships, and predicted protein interactions.
Ingenuity's pathways and networks are available for free in Sigma's Your Favorite Gene powered by Ingenuity tool. There are also several other datasets consolidated in one location, as well as a tag cloud view of PubMed literature.
Try STRING: http://string-db.org/
I haven't used it a great deal, but it certainly produces similar output to Metcore.
HumanCyc plus Pathway Tools provides another set of options. HumanCyc has well curated content on human metabolic pathways. The associated Pathway Tools software will let you paint gene expression, proteomics, or metabolomics data onto the HumanCyc pathway map, and Pathway Tools will also perform enrichment analysis. See BioCyc.org. The pathway painting is available through the web site, but to perform enrichment analysis you must download and install the software.
(My group develops these two tools.)
Thanks to Kissaj for bringing this back to the top. It made me realize it's time for an update about iPathwayGuide.
The application now accepts a wide variety of gene-expression data including:
With these data we provide a free platform to look at your data in the context of Genes, GO Tems, Predicted miRNAs, Pathways, or Diseases. There are a number of advantages to using iPathwayGuide beyond it being 100% free to use, but the key difference is that we use Impact Analysis to score the pathways. This approach uses two forms of evidence to score pathways, enrichment and perturbation.
Some of the new features since my last post in this thread include:
Here's a link to an overview video. http://youtu.be/5maN9krw-nI
Below is a screenshot of the Meta-Analysis.
None of these programs are very good at all - they are all centered around disease, or "model" organisms.
You can also try Ariadne Pathway Studio, they are for pay, but offer a free trial
Course there are a lots of soft-wares you can use to perform a similar analysis:
An important thing is that you design a workflow for the analysis of data that include all of the suggested tool (at least some of them).
Personally, I really enjoy interpreting comparative proteomics results with free tools. Never used IPA

There have been a lot of good suggestions.
I would also recommend GATHER for a quick-function enrichment tool (for KEGG pathways) along with several other categories.
I also developed a tool called BD-Func, which includes some categories that people would probably consider "pathways" (such as transcriptional regulators and some signatures for signaling pathways), although it tends to be most useful for custom signatures.
Of course, there are also tools like GSEA, FuncAssociate, DAVID, etc. (if you are more broad in what you define as a "pathway")
Moksiskaan is an integrative pathway analysis tookit, which supports data sources such as Ensembl, KEGG, PINA, PathwayCommons, DrugBank, GO, SNPs3D, COSMIC, WikiPathways, Tumourscape, and TSGene. Using the provided tools (http://csbi.ltdk.helsinki.fi/moksiskaan/anduril/index.html?q=Moksiskaan%20project), you can prepare all sorts of graph models representing genes, proteins, drugs, pathways, diseases, biological functions, etc. related to your data. Moksiskaan is an Anduril (anduril.org) based open source project, which means that it can be used easily with other Anduril components to carry out complete analyses. Here's one example output: http://csbi.ltdk.helsinki.fi/moksiskaan/archive/ProcessStudy.pdf, but you can find more from the web site and from the supplements of the articles.
IPA looks the best tool to view enriched pathways using P value and FC value. Do you guys know any other platform that could provide enriched pathways from differentially expressed genes? All the platforms that requires gene lists are not so informative because they lack FC values.
As far as I know the only tool that actually uses the FC in the calculation to assess significance of a pathway is iPathwayGuide. IPA uses FC to select for DEGs and to perform its upstream regulator analysis, but still relies on an enrichment model to score pathways.
I cannot say it is an complete alternative to IPA. But you can use GeneSCF for some of its functionality,
Gene Set Clustering based on Functional annotation (GeneSCF)

Pathview Web server provides a user friendly comprehensive solution for pathway analysis, data integration and visualization.
It was recently published in Nucleic Acids Research (NAR) Web Server issue: https://academic.oup.com/nar/article-lookup/doi/10.1093/nar/gkx372
Pathview Web server extends the core functions of Pathview with:
Particularly, the full pathway analysis workflow is shown in Example 4 online.
And you can find more ready-to-run examples on the Pathview Web server: https://pathview.uncc.edu/
I was looking for a tool to identify upstream regulators from a gene set these days and found this!
iRegulon

Download for free from here: http://iregulon.aertslab.org/download.html#download
It works with fly, mouse and human genome but the conservation tool is looking across 7 or 10 genomes depending on how you set the parameters, including the rat genome
I tried it and it is fantastic
Enjoy

I know this is an old post, but it may be relevant to some people. Our company, Advaita Bioinformatics has launched a free pathway analysis application called iPathwayGuide. (https://apps.advaitabio.com/ipg/home). You can sign up for free and analyze gene-expression data for free. The reports offer the following:
You can sign up here.
Hello Andrew, thanks for sharing the link. can I find demo or any teturial will teach me how to use it.
Best
Shaima
I just got charged to download the results :/
Maybe this other Biostar question helps you Any Tools To Identify Significantly Altered Pathways?
Cognoscente (for visualizing biomolecular interaction knowledge) and StarNet (for visualizing gene expression correlation networks) may provide some of the functions that you are seeking.
-Vincent VanBuren
iPathwayGuide is not free anymore. If you want the analysis of the gene expression done you must purchase it.
