Hi Hendrik.

Sure - I would like to share my annotation files. I made a new .ugp
file without problems. Unfortunately, a known issue arises when
creating the new .ufl file.
When importing the ufl information from the NetAffx annotation files
na31, the following warning appears:

Warning messages:
1: In updateDataColumn.AromaTabularBinaryFile(this, .con = con, .hdr =
hdr,  :
  4 values to be assigned were out of range [-32768,32767] and
therefore censored to fit the range. Of these, 4 values in
[42148,51916] were too large.
2: In updateDataColumn.AromaTabularBinaryFile(this, .con = con, .hdr =
hdr,  :
  90 values to be assigned were out of range [-32768,32767] and
therefore censored to fit the range. Of these, 90 values in
[33603,21059245] were too large.

Actually, some frangments are really very large (and other are very
small):

> summary(ufl)
 length          length.02
 Min.   :    7   Min.   :    7
 1st Qu.:  432   1st Qu.:  755
 Median :  679   Median : 1433

 Max.   :32767   Max.   :32767
 NA's   :29333   NA's   :15585

This is different from annotation version na30. (The same issue came
up with the Mouse Diversity Array. I wrote that in another thread.)
Instead of modifying the annotation files and setting fragment length
> 2000 to NA etc., I would prefer to keep the original annotation and
add a parameter to the function for fragment length normalization (max
and min fragment length). What do you think?

Also, I will write to the affymetrix forum and ask why they changed
their annotation.

Best,
Hans-Ulrich

When reporting problems on aroma.affymetrix, make sure 1) to run the latest 
version of the package, 2) to report the output of sessionInfo() and 
traceback(), and 3) to post a complete code example.
