Error: cannot allocate vector of size #12

Open Stacheltier opened 1 year ago

Stacheltier commented 1 year ago

Hi,

we are trying to include flowAI into our pipeline analysing mass cytometry samples. But I get this error:

Quality control for the file: 1 Error: cannot allocate vector of size 4538.4 Gb

I guess it has something to do with memory allocation. But the test file has a size of 1.8 Mbit and the created flowSet 4700 bytes. I tried it also to run directly as .fcs file as suggested in the vignette:

fcsfiles <- dir(".", pattern="*fcs$") resQC <- flow_auto_qc(fcsfiles)

But the error stays the same. I never faced any allocation error in R before I would appreciate any suggestion Best, Sebastian

Hi, It is possible that the file is too small actually and you have a very small number of events. Is it the smallest file you have?

Hi,

thank You for the quick response! I've tried it also with large files (>1Gb). Initially I thought it is a resource problem. Trying around, the import of FCS files seem to be the source of problem. When using read.flowSet/read.FCS /read.flowFrame to import it looks like that "." is introduced as decimal separator resulting in numbers e.g. 0.623 or 1478.2 in some cases. Could that be problema?

During a test I removed all decimal digits during generation of FCS file. Thus, there are no more decimal separators and numbers like above. Afterwards,flow_auto_qc(flowSet_df)works nicely as expected.

Do You have an idea, why I'm facing this data import problems?

best,

Sebastian

Hi Sebastian,

it could be that the problem is in the import of the FCS file. I can't say for sure why this is happening though. Would it be possible for you to share a small FCS file, so that I could try myself too?

Best wishes, Gianni

Dear Gianni,

I guess its really a matter of size. I tested subsamples. The original fcs file containe >900T events each 45 parameters.

I managed to get flowAI working with subset of 50T events. Everything above results in memory allocation error. Thus, it seem to be a matter of my PC.

From statistical point of view: Do You think it is possible to split a sample into subsets of 50T events and run flowAI with subsequent concatenation of results? I would like to avoid to cut down to 50T events since I expect very rare populations below 0.01% of total.

Thank You very much and have a nice X-mas!

Sebastian

Dear Sebastian,

great to hear that you understood what's the problem!

I think that sub-sampling the samples and concatenating them afterward should be fine. You can make sure you always get very similar plots in the report document. If you don't, you might sub-sampling too much.

Have nice holidays and nice Christmas too! Gianni
