Allow target volume/library in a pool to be changed
Currently, the target volume for each library in a pool is fixed at 5µl. In the normal procedure with 21 samples per pool it means a final pool volume of 105µl. Since only 10µl is needed in the next step (clustering), it would be useful to be able to have a lower target volume per library.
The limiting factor is that it is impractical to pick less than 1µl from a library, so if too many libraries have high concentration it adds extra work due to first mixing a higher volume before pooling. On the other hand, libraries with low concentration benefit from this change, since less material is needed.
