QUICK START INSTRUCTION.

If you are a first time user, you can learn how to upload a data set in three steps:
1. Please read the on-line help page by CLICKING HERE 

2. Please download one of sample input files (GDS167) in a format (soft, csv or txt) to your hard drive (e.g. C:\temp\). If you downloaded the SOFT format file (GDS167.soft), the uploading process would be almost automated. If you chose csv or txt as an input format (GDS167.csv or GDS167.txt), you might have to enter several parameters for the data set. For the sample data set (GDS167), there is a simple two group comparison between wild type mouse samples (wt1,2,3) and  transgenic mouse samples (tg1,2,3).

3. Select group number "2" for the testing sample data set GDS167 from the pulled-down menu ("Select group number:") below. Then, you can click the button "Browse ..." to open your file (e.g. GDS167.soft) in your hard drive (e.g. C:\temp\).  Finally, you can click the "Upload File" button. Please find the correct parameters for GDS167.txt or GDS167.csv here.
The uploading performance may vary depending on many factors. For a regular DSL (1 Mbps) connection, the predicated time for a file to be uploaded is around 40 seconds per 1 MB file size. If your file size is larger than 6 MB, you might receive a "time out exception error" or "Internet Explorer cannot display the webpage" from your browser. In this case, please make your file into the NCBI GEO "SOFT" data format and contact us for the special FTP uploading.
