Hi all I'd like to look specifically at a subset of genes, those that are located on one chromsome, and amongst these, those genes that are N fold changed in ...
Adrian, You can use "Tools/Gene list by annotation" to export chromosome A genes and then use them as filter on or compare on gene list. Cheng ... From: Adrian...
I've already used 1.2 version and recently updated with 1.3 version. But different results were obtained from same array data with same options after using 1.3...
Cheng, Many thanks for the help below. I find now that I look at that particular chromosome that is is substantially upregulated between control and...
Dear Cheng, When we analyze large datasets of several hundreds to more than a thousand chips, the performance of dchip normalization and model- based...
Wenzhong, Currently dChip cannot do these. You may consider using PSI file: http://biosun1.harvard.edu/complab/dchip/model-based%20expression.htm#psi_fi le ...
Dr. Li, I have a statictic question to you related to set up the subset for dChip data analysis. I am working on a dataset of 16 chips of primary cancer cell...
Aiguo, It's not required to use the same array as before for normalization. It's better to analyze all arrays in one group and normalize to the same baseline ...
Hi, When I use genome view the mapping stops before finishing all the chromosomes. Also, are there any reccommended machine specs for dCHIP1.3+? thanks jason...
Jason, Can you paste the dchip error messages? A general Windows system is ok for dchip 1.3. Cheng ... From: sjorges2002 [mailto:sjorges2002@...] Sent:...
Cheng, Sorry to bother I fed the wrong annotation file. Is there any way to change the max stretch limit? I have a windows system. I'd like to know what kind...

Hi all, I am attempting to load some of Affy's reference data for the human 100k Xba/HindIII chip I into dChip. I have the CEL, CHP, and EXP files, as well as...
Ah, so what is the maximum SNP count that dChip can handle at once? And is there an ETA for even an alpha or beta version of dChip SNP that can handle 50K or...
Hello dChip group, I am trying to use the Chromosome function and am getting some error messages. Can anyone point out what I might be doing wrong? {View data...
David, The refGene.txt and refLink.txt files downloaded form UCSC <http://hgdownload.cse.ucsc.edu/downloads.html> need to be combined by Microsoft Access to...
hi! Cheng: I have multiple samples from 4 tissue types. I think it was recommended to do the MBEI per tissue type separately. Could you tell me how to compare...
hi! Cheng: I think I got the answer, I found this from Dchip Manual: "This requires putting different tissues in different dChip groups (e.g. create a...

I would like to see the normalized values for an external data set. After I "Get External Data", I chose "Normalize" to perform the normalization. Then I...
hi! cheng: My understanding of the situation is as follows: 1. if there are very different tissues, then put them to separate group and do normalization...
Hello dChip users: I am new to the software program and am in need of some assistance. We are currently trying to analyze our Map10K SNP array data with dCHIP,...
Hi, Does anyone have a prebuilt Drosophila 2.0 chip Genome information file they could send me? I thought one could be built fairly quickly with the make...
Hi guys, Attached please see a hierarchical cluster of some of my data obtained by dChip analysis. Now, the cluster itself, I can comprehend perfectly, while...
