"Affinity Profile"
« on: January 01, 2019, 04:58:35 am »
Hi,
I am a new user of REDUCE suite.
Is there anybody to help me in using "Affinity Profile". How could we find the PSAM file for our DNA queries to run the computational calculation of binding affinity.

Best Regards,
Mina

Hi Mina,

Thanks for using the REDUCE Suite and for posting your questions on the Forum.

Type AffinityProfile -h, and try the examples, on how to use the program. PSAM is a MatrixREDUCE-specific term and can be derived from running MatrixREDUCE. You may also run Convert2PSAM to convert commonly-used formats to PSAM. As with AffinityProfile -h, you can type -h or --help of these programs for helpful information with examples.

You may also want to try other (more sophisticated) software tools developed by the Bussemaker Lab.

Best regards,

Xiang-Jun

What examples of how to use the program are you exactly referring to, Xiang-Jun?

Please see http://reducesuite.bussemakerlab.org/documentation/affinityprofile/ which you get by "AffinityProfile -h".

Hello

I'am also novice for using your great package REDUCE_Suit.
I'm interested to study the affinity profile for a vary famous gene COL1A1( I downloded COL1A1 from Ensembel database) I tried to understand the dynamic of affinity profile for a transcription factor Sp1 through its binding site for both wild and mutant COL1A1 genes .

To start my study I ran the commande :
AffinityProfile \
   -prefix=aff_ \
   -threshold=0 \
   -psam=../../Desktop/source/REDUCE-Suite-v2.2/examples/AffinityProfile/psam_001.xml \
   -sequence=sequence_COL1A1.fasta

As a Psam matrix, I used the matrix given in your example.
But then I don't understand the result.

cat seq_psam.dat
   psam_001.xml
NM_000088.3   0.0301094
####################
cat AffinityProfile.log
sequence file: sequence_COL1A1.fasta   cut-off: 0

Could you please help me to understand these results ?
What is this matrix  "aff_psam_001.xml" ?
How could I obtain more details on the affinity change and dynamics of binding site ?

Thank you in advance
Best Regards

Azadeh

Hi Azadeh,

I'm glad to hear that you have got the REDUCE Suite up and running.

Interpretation of the results, however, is beyond my scope of support. Reading publications from the Bussemaker lab may help.
