It can be used when describing something that is challenging to recreate or piece back together, often in contexts related to information, memories, or physical objects.
Example: "The ancient manuscript was damaged, leaving parts of it missing and difficult to reconstruct."
Alternatives: "and hard to recreate" or "and challenging to piece together."

However, the semantics of such selections often depend on specific parameter settings and it can be difficult to reconstruct them without additional information.
This promiscuity as well as numerous ancient and lineage-specific gene and domain duplications make it difficult to reconstruct the relation of VRN1 to other B3-domain containing proteins.
Molecular functions arise from complicated sets of physical interactions between large numbers of proteins, RNAs and various regulatory pathways, which can be difficult to reconstruct, represent and analyse.
Current methods for both in vivo and in vitro imaging of microvasculature are time consuming and the resulting data are difficult to reconstruct.
Biological hypotheses, including hypotheses about mechanisms, can often be tested experimentally, and some such tests are difficult to reconstruct in terms of causal reasoning strategies that were discussed in the previous section.
