iPathwayGuide Frequently-Asked Questions

When one shares a report with somebody else, the recipient gets a link and they will be able to access the report and do everything that the owner can do. The owner has the opportunity to decide whether the recipient is allowed to share the report further. Once the recipient clicks on the link they will be sent to the application to accept the share; they will then go into their account and click the accept share button. Once the link has been used it cannot be reused. So if a recipient of a share forwards the email to somebody else, the second person will not be able to see the report. This is by design so data cannot be shared without the permission of the owner. Also, if one clicks on the same link more than once, the second time, the link will not work.

On your dashboard, you can click on the little shopping cart and then click on “purchase with balance.” The report will become available right away.

On the Pathways tab, on the right hand side, “pathway details” then “Gene table” then the “+” sign. When you click on that, you will see a table with the genes on the pathway. there you can sort, search for specific genes, etc. You can also download the entire table with the usual download icon.

When you change the p-value, the number of differentially expressed genes will change. That in turn, will change every single results in every single type of analysis performed: GO terms, pathway, upstream regulator, drugs, mechanisms, etc. The results will be an entirely different from the results before. Hence, this will be a new analysis. A good thing to do is to analyze your data with a couple of different thresholds and then do a meta-analysis of the results. this way, you will be able to tell whether your conclusions change depending on the threshold used. Obviously, you would place more trust in findings that remain the same regarding of the threshold used.

The answer here is very similar to the one above. When you change the organism, the annotations will be different. This would be a totally different experiment basically. This is an additional reason for which this has to be a different analysis.

iPathwayGuide supports directly human, mouse and rat. For other organisms, you need to first map your genes to orthologs. Many of our users have done this very successfully.
Here is an example in which iPathwayGuide was used to make important discoveries involving mackerel and sardines:

Transcriptomic analysis of short-term 17α-ethynylestradiol exposure in two Californian sentinel fish species sardine (Sardinops sagax) and mackerel (Scomber japonicus).

When you complete and publish your research, please share it with us. We will be happy to make your research more visible by sharing it with our users.

The basics are always the same regarding of the assay. The first step is to map the results of your assays onto genes. The assay can be very different but in most cases you can map the results on genes. For instance, for a methylation assay, you could associate each differentially methylated region to the gene immediately downstream of it. There will be some that won’t be mapped, but most areas that have an effect on transcriptional control are expected to be mapped correctly. Then you calculate an effect size. that can be a log fold change of differential expression or differential protein abundance or methylation, etc. It is often possible to calculate a p-value, as well. Once you have genes, effect sizes, and p-values, you can upload this in iPathwayGuide. You should specify the type of assay the data came from so you can do a meta-analysis later integrating multiple types of data, if those additional data become available.

Regarding the figures, you need to download them in .SVG format from iPathwayGuide. Any downloadable figure in our software can be downloaded as SVG. The SVG is a scalable vector format that can scale to any size and offers perfect resolution. Since we are talking about images, please keep in mind that you can customize most figures. In some, you can even select the colors. In many, you can select which genes to include and in which order. Please contact us if you have any questions about these capabilities or if you want to have a short meeting to show you how to do any such customization.

Please make sure your are using the “…gene_exp.diff” file that comes from CuffLinks. There are some applications that claim to emulate CuffDiff output (e.g. Galaxy). If you are using one of these applications, please make sure the output file has all columns populated. See below for specific columns that must be present. Also, use this link to view the Cuffdiff manual.

It is a great idea to use the software and explore the capabilities before making a purchase. The way to do this is to create a free account on our web site www.advaitabio.com. Once you create an account, you will have full access to several analysis results. These datasets cover a range of experiment types, conditions, and analysis outcomes. You will be able to fully use the software to explore these data sets in whichever way you choose. You will have full access to interact with all of the demo analyses and experience all of the features of iPathwayGuide. We also provide sample data files, which will show you some of the formats that can be used to upload data for analysis.  An alternative would be to setup a time and let one of us to show you around the software. You will learn more in a much shorter time, and you will also be able to get immediate answers to any questions you may have.

We report the ‘Creation Time’ based on Coordinated Universal Time (UTC).

A novel signaling pathway impact analysis

GEO2R does not perform normalization for Affymetrix CEL files. The Advaita iPathwayGuide CEL file uploader currently utilizes the Gene-chip Robust Multi-array Average (GCRMA) normalization method. As such, there can be discrepancies between CEL files processed with GEO2R vs. iPathwayGuide.
