Macro for Batch Export of CSV in C.01.10

Hello,

Would you mind clarifying what you mean by exporting to csv? Are you looking for a summary report for a batch of samples in a .csv format or do you want the raw data x-y coordinates from the detector signal exported for each injection in a batch to a .csv file?

I am looking for the raw data x-y coordinates for each injection in the batch following integration in order to create an integration table with areas, percentages, and retention times as well as overlays of each injection via macros that I have made in excel

Hi howard_sanford, 

Thanks for that option. The report CSV doesn't really give me all that I am looking for, and then would require a good bit of deletion in order for my macro in excel to work. 

One question about the Signal CSV export option. It appears that each time I close and reopen Chemstation, I will need to reload the macro into the command bar in order for the signal CVS files to be export. Does this seem accurate

Thanks a lot for sharing. Recently I am trying to install this script in our OpenLab system by following what the post described. But seems that cmd from OpenLab cannot recognize the CSVxport file, which I think might be because the file needs to be a true .mac file, and modifying the format by changing the name would not work. Do you have any comments and suggestions?

Hi biocatchen,

For ChemStation the standard macro .mac file is a plain text file, so the instructions above for changing the extension on the attached file from .txt to .mac will allow ChemStation to load the macro file. There are also 'compiled' .mcx macro files, and only changing the extension on a file will not produce one of these macro files, but it is not necessary for the macro to be in this format. 

Are you trying to get this macro to work on OpenLab ChemStation edition, or on OpenLab CDS 2.x? The macros discussed in this post are only for ChemStation edition. There is some discussion in this post about preforming x,y chromatogram exports in OpenLab CDS that may be helpful if you are using that product. 

Thanks a lot, howard_sanford for the prompt reply. It works now and initially, the macro file was somehow named as .mac.txt file rather than .mac file. Now it generates a list of separate cvs files with each sample having three signal files (DAD1A, DAD1B, FLD1A). Just wondering if there is a way of only generating one signal file like DAD1A. I greatly appreciate it.

biocatchen,

The macro prints all loaded chromatograms, so you can edit your method to only load the DAD1A chromatogram and that will be the only one exported. Otherwise you could edit the macro so that a particular chromatogram type is the only one exported.

Hi howard_sanford,

first of all thank you for posting this macro, it has been very helpful for me and my colleagues.

We were wondering if this macro could be implemented to obtain a single CSV file containing all the signals from each sample in the run, so that we don't have to open each individual file and merge the single signals for every sample (we work with 50 samples per run and it is quite painful to process them). Ideally it would be great to have also a single file containing all the RTs and peak areas per sample, again to speed up the processing and get the concentration of the compounds.

This macro would save us an incredible amount of time if it would be possible to obtain.

Thank you very much in advance!

Hello mfp_sadler ,

I'm glad you found that useful. The previous change I made was a very minor change to a very old user contributed file. I don't believe this macro could be easily modified to put all the results in one file. You could check the macro given as the other solution to see if that may be easier to modify. Or it is possible another user has something that they may be able to share that is closer to what you want.

You could also try to search for a batch file or shell script that could concatenate the files and do something like placing the file name in between each section. 

For getting all the RTs and peak areas into one file you could investigate using a Sequence Summary report. This can be set in the Sequence Parameters under Sequence Output.
