Hi,

did you have the chance to look at my data I sent you about 2 weeks ago? I am a little bit under pressure to evaluate my data. I would like to use BioMap but if it is not suited for my data I need to find something else. Would you please be so kind and give me a note whether your software is good for my data or not?

You mentioned a paper from Rausch et al about a special sequence for recording perfusion data. Could you please give me the year, when it was published (you wrote MRI 200X)? Thanks.

Hi, I emailed the files in 5 pieces and also ftp-ed a tarred and gzipped file to your server a week ago. Did you have time to look at it? Are your results of our data close to that what is expected?

[kbockhorst]

I would appreciate a lot if you could have a look at my data. It is a 15 MB tarred and zipped file, containing everything beside the FID file. Please tell me, where to send it to.

[kbockhorst]

My results are still far off the expected values. here is what I do:

transform 2dseq into analyze format
load scan
start DSC-PWI
adjust the intensity threshold from 200 to 5 (values range between 0 and 128)
I set TE, TR, cutoff time 40 s, baseline end 22, amplitude cutoff 0.3, … and create maps with procedures/atd model/map. I get the four files ending
…c, …a, ….t, .. d.
I use tools/probe AIF and get the response cluster analysis not possible, number of valid clusters only 0.

Any suggestions what went wrong? Is this a common error message?

[kbockhorst]

‘Perfusion analysis can just be done for data, which was already stored in the database’ was your response to my question. Does this mean, one can not directly use Bruker’s 2dseq files but has to transform them into another format, i.e. Analyze format. Do you understand this as ‘storing it in the database’? Or how would I do this?

[kbockhorst]

The ctc map is – I guess- the most simple map to generate. I do not need any AIF. Still, this is the only window, which remains blank, better, homogeneous grey.

Can I read the Bruker files directly into the perfusion analysis or do I have to import them first into Analyze format?

On page 52 of the manual, last line, it says the files are stored on disk as GpDF_a, GpDF_t, GpDF_d and GpDF_c. The files on my Tiger Mac (it finally works, thanks again!), my Linux Redhat and WindowsXP end atd_a, atd_t, .. That’s just the same thing, right?

[kbockhorst]

Ja, hervorragend, it works! Thanks a lot.

I recently (September 05) tried to install IDL 6.2’s VM to run BioMap on a Tiger Mac. I got the same errors as srmaster had with IDL 6.1’s VM. Is there hope the issue might be solved one day?

[kbockhorst]

I did as recommanded and edited the uparsrc file in my Application Data\BioMap directory (The main path of the Application Data did not include the BioMap folder).

After I edited this and a few more paths the error message at the begin (The path might not have been set up correctly…) disappeared and the folder icons reappeared.

Thanks

I did run the install.bat several times. As suggested, I added the licenserc file to that folder before I ran installsettings.bat. I repeatedly deleted and recreated the settings in my personal C:\Documents and Settings\kurt\Application Data\BioMap folder. Still no folder icons in the defaults widget. And right, I do get a widget with the comment that the BioMap path might not have been set up correctly after starting biomap. Also the Bruker import does not work because of the settings, I guess… And I am running Windows XP.

[kbockhorst]

Thanks,

what units do the maps have? MTT in seconds, CBV in ml/100g, CBF in ml/100g/min? Are these the units for the other maps, too (ttp ins)?
