I loaded a CuffDiff file but I cannot see it.2019-01-10T19:41:19-04:00

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.

Column number Column name Example Description
1 Tested id XLOC_000001 A unique identifier describing the transcipt, gene, primary transcript, or CDS being tested
2 gene Lypla1 The gene_name(s) or gene_id(s) being tested
3 locus chr1:4797771-4835363 Genomic coordinates for easy browsing to the genes or transcripts being tested.
4 sample 1 Liver Label (or number if no labels provided) of the first sample being tested
5 sample 2 Brain Label (or number if no labels provided) of the second sample being tested
6 Test status NOTEST Can be one of OK (test successful), NOTEST (not enough alignments for testing), LOWDATA (too complex or shallowly sequenced), HIDATA (too many fragments in locus), or FAIL, when an ill-conditioned covariance matrix or other numerical exception prevents testing.
7 FPKMx 8.01089 FPKM of the gene in sample x
8 FPKMy 8.551545 FPKM of the gene in sample y
9 log2(FPKMy/FPKMx) 0.06531 The (base 2) log of the fold change y/x
10 test stat 0.860902 The value of the test statistic used to compute significance of the observed change in FPKM
11 p value 0.389292 The uncorrected p-value of the test statistic
12 q value 0.985216 The FDR-adjusted p-value of the test statistic
13 significant no Can be either “yes” or “no”, depending on whether p is greater then the FDR after Benjamini-Hochberg correction for multiple-testing
How long does an analysis take?2018-08-22T08:40:42-04:00

Generally, each analysis takes about 15 minutes to complete. If there are other analyses queued ahead of yours, it may take a bit longer. You will receive an email as soon as the analysis is complete.

Do you offer a free trial?2019-06-13T11:26:55-04:00

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.

Once you get oriented with the software, if  you want to see an analysis of your own data, we offer the possibility of purchasing a single analysis. We need to charge for this because we use a backend cloud platform that costs us money for every analysis done. The price of a single analysis is meant to cover these costs. The price of the single analysis is USD 287, as of June 15th, 2019. Please see more details at https://advaitabio.com/blog/. A single analysis can be purchased with PayPal by clicking the Purchase button next to it.
Any analysis provides a full interactive report that you can use to further explore your results in many ways, including discovering mechanisms. The interactive report can be shared with others at no additional cost. The price also includes a PDF report that many of our users use as the Methods or Supplementary Materials in their published peer-reviewed articles. This automatically-generated PDF contains a full description of your input data, experiment, methods, results with figures, and references.
Once you see the capabilities of iPathwayGuide in action, we strongly suggest that you get a subscription rather than continue to purchase one analysis at a time. We will gladly refund the price of any single analyses done in the 30 days prior to ordering a subscription.  See the blog discussing single analysis vs. subscriptions at:
Do you have a legend to help me read the various diagrams?2019-06-18T17:10:41-04:00

Here are the legends describing the symbols used on the pathway diagrams, gene networks and GO directed acyclic graph, respectively. Click an image for a larger view.

Can I share a report?2018-08-22T08:49:40-04:00

Yes! From the dashboard, just click share on any completed report. Then enter the email address for the person you wish to share it with. If they do not have an account, they will be prompted to create on. Once registered, they will be able to view the report.

Why is the ‘Creation Time’ different from my clock?2018-08-22T08:50:16-04:00

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

What browsers do you support?2018-08-22T08:51:10-04:00

iPathwayGuide is designed to work with all the latest major browser platforms:

  • Google Chrome

Do you have a sample files I can try?2018-10-13T11:09:13-04:00

iPathwayGuide works with the most popular differential expression files. Some 3rd party emulators (e.g. Galaxy) may structure their data slightly differently. Click on the sample files below to see the structure of these files.

How should I cite iPathwayGuide?2018-10-30T12:33:43-04:00

Citing iPathwayGuide

Using Advaita Bio’s products or content for any form of publication (e.g. print, electronically) requires researchers to cite them. Please use one of the options below for citations:

• “The Data (significantly impacted pathways, biological processes, molecular interactions, miRNAs, SNPs, etc.) were analyzed using Advaita Bio’s iPathwayGuide (https://www.advaitabio.com/ipathwayguide).”

• “This software analysis tool implements the ‘Impact Analysis’ 1 approach that takes into consideration the direction and type of all signals on a pathway, the position, role and type of every gene, etc., as described in (Draghici, 2007, Donato, 2013).”

• LaTeX users may use the following code in the bibtex file:


author = {Advaita, Corporation},
title = {Pathway Analysis with iPathwayGuide},
month = Jun,
year = {2014},
url = {https://advaitabio.com/ipathwayguide}

Why do I get different results with GEO2R vs. your CEL file uploader?2018-08-22T08:57:29-04:00

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.
